On the sizes, the smaller it is, the more rigid it will be and the more tolerant to mistakes it will be. If you’ve never 3d printed or used a CNC, then there is a lot to learn. It’s much better to build it small (and probably pretty short too) until you get through a least a few operations. I personally think this is especially true for 3d…[Read more]
I made a reply but it timed out and I wasn’t logged in any longer.
Basically, instructions are much clearer now that you said that the instructions included methods for leadscrew or all thread.
If my counting is correct, I will need two spacers (one as is required plus one to replace the nut lock spacer).
Then I will just need a coupler from…[Read more]
I think if you have a look through the assembly guide you will see all the answers. I will try to run through them here but since this is easily sourced worldwide I have had to make a few parts interchangeable and different sizes.
If you use the T8 leadscrew you do not need the coupling nut. The coupling nut and T8 brass nut are serving the…[Read more]
Been lurking around the website for about two weeks now after finding an instructable that credited the original designer and lead me here. This project seems to check all the boxes for what I have been searching for as a hobby. I am a student majoring in Computer Science, and I have an interest in making things but haven’t been able…[Read more]
Software guy here, suggesting that you can use M666 to adjust each endstop instead of the mechanical solution of the screws.
If you set it up right, and one endstop is 1mm behind square of the other (for example) then you should be able to set that with M666, and it will stretch to bump the endstop, and the retract 1mm away from that farther…[Read more]
So, you flashed with estlcam firmware? You shouldn’t do that (stick with the Marlin FW).
I’m not familiar with that procedure. Your Power supply is 24V, and you removed a diode, so nothing is powering the arduino, except USB? Can the drivers handle 24V?
What evidence do you have of that? Do you get a response from an M115…[Read more]
This is typically how we test it, https://www.vicious1.com/assembly/software/
Your previous statement might mean that is not an option now.
Where did you buy everything?
Are you powering both the ramps and the arduino?
I am almost finished building the MPCNC. Everything is assembled. I am testing the stepper motors on the ramps board before I install them on the printer. I have the ramps board communicating with repetier. When I first power up the board the motors click but I can’t get them to move or do anything. I have also tested in ESTLCAM. The board…[Read more]
You were lots of help. Some of it is just going to have to be trial & error. I did notice something I did not expect with the purchased drylin Igus bearings. With the tighten gap I left in the middle bushings tightened a little too much for a smooth movement of the rod, but the side ones work good. The difference was in orientation of that slo…[Read more]
Thanks for the perspectives.
The main motivation for the change is that long jobs cannot be paused and resumed without leaving the CNC control box powered on. There was an incident the other day when somebody shut down a PC with Octoprint open, and this somehow resumed the print with the router turned off. Needless to say that wrecked the project…[Read more]
