    Free for enthusiasts for 1 year, at the end of 1 year you can resign up for enthusiast again! This might be it, the real deal, everything all in one. It has CAD, CAM, Render, 3D Print, motion, Blender type mesh modeling. Everything all in one. I’ll be testing this out, I have already done the 2D CAM tutorial and it looks great.

    I suggest you get it while its free, just in case!

    I downloaded fusion as well and am about to start to play with it. Autodesk has really great free licenses to encouraging hobbyists and students.

    What Tutorial did you do? I found this one:https://www.youtube.com/watch?v=o-GBpUZ3piY .

    Once you get it installed and running the tutorials are step by step walk through. The tutorial must be from a different version because the bit selection is kind of off but once you figure that out it is easy. Really nice software…just need to get that rotating axis in there so I can make another add on!

    All of Autodesk’s software suites are free if you sign up with a EDU account. As a matter of fact, I don’t think you even need an edu email, you just say you’re a student…hopefully you’re and you can download anything if I remember correctly.

    Wanted to start a thread on post process for fusion360. I’m starting with just getting the post process to output gcode that repeitier host can work with. So far you still have to strip out everything above the start comment and strip off the trailing space at the end of the gcode. I’ll work on stripping out all of the unused commands at some point.

    Question was asked about post process file

    Thanks for sharing this post processor. Just tried it out briefly with one of the CAM examples in Fusion 360. What are you using to send the g-code?

    I use Pronterface, and it wants a “.gcode” file extension, where this post processor outputs a “.tap” file. This is not so important, as Pronterface can read the .tap, but then the comment syntax causes an error (“[WARNING] raw G-Code line “/” could not be parsed”). Pronterface reads comments with a semicolon “;” rather than the “/”.

    I found a post processor for Marlin a while back (link not included as comment won’t post), which seemed to work reasonably well, but tried to home the machine (as a 3D printer would) at the beginning of a toolpath. I made a few adjustments so so that it zeros the machine at the start and sends it back to zero at the end. I just compared the output of your script to the one I have, and noticed some differences in the length of the file, probably just caused by using different tolerances (yours is longer, so I suppose it makes smaller moves).

    I still don’t have my machine cutting yet, but have done a few simple tests with a pen, and the g-code produced by the post processor I have seems to work OK. Haven’t tested yours out, but was wondering if yours can pause for tool changes. Is that even possible on a Marlin based system? Would that depend on the g-code sender?

    Here’s a link to the modified post processor I have used: http://1drv.ms/1La44X8

    What are you using to send the g-code? – I’m using Repetier Host

    comment syntax causes an error – working on stripping all this out.

    can pause for tool changes – haven’t got that far yet; however, I know in marlin you can insert an @PAUSE command and will lift the head. Actually you can customize what the @PAUSE command can do, such as lift and move to a given x,y position.

    Here’s a link to the modified post processor – I’d be happy to work with you to get a decent post processor working. I really like Fusion360 so far. Thanks for the link, I’ll check it out.

    Working with the marlin.cps post process produces better gcode than the version I started on. I’m going with the marlin.cps as the base to work with. Might not have to change anything.

    So I tried replying to this thread two days ago, but obviously my comment didn’t appear. Glad to hear the post processor is working for you. The onedrive link works then?

    I did a few comparisons between the two and noticed a difference in file length. marlin.cps produces a shorter file with less g-codes, but I suspect this is simply due to tolerance settings.

    So I suppose the next thing is to make any improvements. There are a few unnecessary codes that are produced, like setting the tool number and turning coolant on and off. Are there any codes that need adding? I thought having a way to pause the machine for a tool change would be useful, otherwise it would mean making multiple files for each different tool. How often do people change tools on the one piece?

    The link works, just didn’t wait long enough (patients man patients)haha

    I think the first thing I’m going to work on is tool change. Should be easy to replace the tool change code with an @PAUSE.
    The @PAUSE command will run any custom script you want but by default I think it lifts the head and moves the carriage away from the work piece. I’ll do some more testing when I get some time.

    I am jealous I haven’t spent any time with fusion at all. I am glad you guys are getting all the kinks worked out though. When I do get a chance to sit down with it, it should be smooth sailing! Keep up the good work!

    Here is the first of five videos “How to learn Fusion 360 CAM – Basic – Chapter 1”

    He does a nice job of going over the basics.

    using the supplied c code post process script I was able to make code that my machine recognized! Hurray! However the feed rate is impossibly slow. My g code is set in MM and its feed rate is .2 A line looks like this

    N60 G1 X392.5 Y-339.487 F2000 (moving quick)
    N65 G1 Z15 F2000 (quick z)
    N70 G1 Z5 F2000 (still quick z)
    N75 G1 Z-5 F0.2 (unnnngggggg)

    Where in the config file, or autocad can I change that feed rate?

    Hi Alex,
    I haven’t managed to spend much time on this recently, and I’m no expert, but I think what you need to do is check your plunge feedrate setting in Fusion 360. When you add a new toolpath, in the little sub-window, underneath the tool choice menu, it has a “Feed & Speed” menu. This is where you can set the feedrates for the chosen tool. If you have designed your own tool, then these settings can be allocated when you set the default tool values.

    Make sure your plunge feedrate is set to the speed you want. In your g-code above, it appears that your movements are at 2000 mm/min, when the tool is just being positioned, but when it plunges into the material, the feedrate is set to 0.2 mm/min.

    I have attached an image highlighting the option. If this is not the problem, then I’m stumped.

    That was part of the problem. I think I’ve isolated the issue. the machine believes it can move the z axis up quicker than it actually can leading to a deeper next cut after each lift. I’ve discovered that if the machine is asking a stepper motor to move quicker than it can the motor makes its normal move sound followed by a short series of moves instead of one continues move.

    I have set repieter host to use the proper z axis move rate (100mm/m) but that doesnt appear to have an effect once I run g code. I did a find a replace (on the g code) and changed the feed rate for returning to the clearance plane. This lead to a mostly successful run, and totally eliminated my z axis problems

    I am currently editing the marlin firmware to set a lower max on the z axis rate. I’ll report back if that fixes things

    And that was it. A week of struggling with software to find out that its the firmware on the ramps board that was the problem. I never checked to see if the right firmware was uploaded when i bought the kit. I downloaded the latest from the thingverse page and wam. Things working as expected.

    I hope this helps someone else

    I think the latest estlcam update to version 8+ changed something that is why I updated the firmware. These weren’t issues before. I’m sorry for the hassle but I’m glad you are up and running now. I’m doing my best to stay ahead of the issues. Everything is working much better now, chalk it up to growing pains and not spending thousands of $$$$$ on software. I’ll take a few bugs here and there over a lighter wallet any day.

    no worries. Its good to learn these things. And even if I factor in my time for finding this out I am still many thousand ahead 🙂

    Fusion360 Post process
    I have a working version of the Marlin.cps modified for Fusion360.

    Example output of a simple box with Face 1/2″ bit, and contour 1/8″ bit
    Notice the M1 command for the tool change, requires user to press the button on the lcd panel to continue.

    Thanks for the post file. What are the differences between this one and the earlier one? Just the took change pause? For my 3D printer I did a Marlin firmware change to pause, beep and lift out the of way for a filament change.

    I tried to eliminate all commands that Marlin firmware doesn’t support.

    Thanks! So the changes basically eliminate some unsupported gcode generation with “;” insertions in some functions and “//”‘s out other functions all together. You also bring Z up 15mm on a tool change.

    One thing I did not figure out is what happens at the very end. Does it not return to the origin? When I used the original “post” file the tool seemed to lift, then dropped to the model surface again then returned to the origin while dragging across the model surface. I thought that this was just a problem with my Fusion CAM settings. I still may misunderstand the meaning of some the different height settings in CAM. Is there any way get to simulate the entire tool path from and to the origin? Even with full tool path selected it just starts and ends at the milling operations.

    Sorry I have been too busy/lazy to run the diff above 🙂 I will eventually get around to running the new version to see what happens.

    If you look at the very bottom of the post file there is a section called function onClose() {

    You can put anything you want into this section and will get generated at the end.

    To go back to zero just add these two lines.

    writeBlock(gMotionModal.format(1), “Z15”); //added to return tool to 15 height at the end ;Please don’t drag my bit across the work surface, lol
    writeBlock(gMotionModal.format(1), “X0”, “Y0”); //return to zero

    So the onClose function becomes:

    function onClose() {

    writeBlock(gMotionModal.format(1), “Z15”);
    writeBlock(gMotionModal.format(1), “X0”, “Y0”);

    writeBlock(mFormat.format(84) + “; Turn steppers off”);

    To answer your question about the simulation. Fusion 360 simulates the cut path, not the final gcode generation.
    If you want to simulate the gcode you would need to load the gcode into a CNC simulator.

    I haven’t found a good simulator that is free yet; however, you can do a 30 trial here = http://www.tkcnc.com/

    Worked ok for me.

    I just downloaded and registered Fusion 360. I’m very excited to start learning a real cad/cam program.

    I have a couple of questions:

    About the tool change – how do you re-zero the z axis after changing the tool, or is that what that ReturnToHome code does?

    Also, how do I use all these bits of code in this thread?

    Generally I don’t try to shove every tool path into 1 gcode file.
    I break up the post process by bit size.

    In Fusion CAM side, just select the tool paths with the same size bit and for the post file select the MPCNC_Fusion360.cps

    To rezero you can move the z down until the new bit barley touches the surface and issue a G92 Z0 manual command in Repetier-Host.

    If you look at the sample gcode I posted, at the very top there is a G92 X0 Y0 Z0 – that sets the xyz axis to zero where the bit is currently at.

    Can have a quick bullet point list of how to export from fusion?
    I have been able to access the post process but there are options for 50 or so cnc machines. Not quite sure what to do now…

    Just got back to looking at the post and noticed that the zip MPCNC_Fusion360_ReturnToHome.zip with file MPCNC_Fusion360_V2.cps has some odd characters in the third and second to the last writeblock():
    writeBlock(gMotionModal.format(1), “Z15”);
    writeBlock(gMotionModal.format(1), “X0”, “Y0”);
    I just deleted them and added your suggested return to home but with a 5mm Z offset. I also changed what I think is the initial home Z offset to 5mm.

    The attached file contains the edited post.

    Fusion 360 does not have an Marlin/MPCNC post processor file in it’s default configuration so you will need to download the one initiated by WorkerDrone and tell Fusion 360 to use it. Try my slightly modified version attached here.

    OK – here is my attempt at some bullets for you:
    * Download and unzip the attached MPCNC_Fusion360_V2_RTH.zip to a convenient folder.
    * In Fusion 360:
    * Generate tool paths and simulate
    * Select tool path or paths
    * Select Post Process
    * In Configuration Folder section select Setup and browse to your convenient folder
    * In Post Configuration section select Open Config and select MPCNC_Fusion360_V2_RTH.cps
    * Select an output file location and name
    * Select Post
    Please let me know if anything is unclear or wrong.
