If anyone is looking to run GRBL on their existing Mega and RAMPS, here is a project that I forked and setup the defaults to MPCNC settings. You may want to tweak the acceleration numbers as I used the settings that are in the beta firmware, but things are running OK over here…BryanParticipantDecember 10, 2015 at 4:17 pmPost count: 58
What would be the benefits of running GRBL? More in-tune with the Shapeoko folks?
Are there any drawbacks/things I would be giving up if I switched?mschrockParticipantDecember 11, 2015 at 7:42 pmPost count: 11
I’ve only tested the above code with Easel. I attempted to try Chilipeppr, but was unsuccessful. The only real advantage that I see is you aren’t bound to Estlcam, and are using firmware that is used with lasers, mills, and routers. Marlin is a 3D printer firmware and while based on GRBL, it is heavily modified for 3D printing.mschrockParticipantDecember 12, 2015 at 7:37 amPost count: 11
I should probably add that this should be considered beta.WalterParticipantJanuary 26, 2016 at 6:06 pmPost count: 186
How did you get this setup using easel? ive gone through the machine setup page but I can’t seem to get it to see my board. Do I use the X carve settings or the shapeoko? I’ve installed easel local and that hasn’t seemed to do anything but tell it not to have me download easel local again. im stuckWalterParticipantJanuary 27, 2016 at 1:26 pmPost count: 186
also, will this work with one of the full graphics displays that allted sells?Leo69ParticipantJanuary 27, 2016 at 4:15 pmPost count: 342
I do like the expanded gcode command set in grbl and I’m seeing some host software with Camera integration which is really cool. What I’d love to see is implementation of G68 and G69 codes to rotate an axis.
Still grbl is tight code made to run on a memory and io limited uno and cnc shield. Wouldn’t it be easier to add the functionality of grbl to marlin firmware? I plan to use my mpcnc with an extruder at some point so i don’t want to give up that ability.WalterParticipantFebruary 16, 2016 at 8:20 pmPost count: 186
I’ve just decided to build 2 separate controller buildouts. One for printing, which I’ll mostly be doing with mine. and one with grbl for using with easel, because I don’t need much more functionality than that.BastiParticipantMarch 19, 2016 at 3:57 amPost count: 1ScottParticipantMarch 25, 2016 at 12:45 pmPost count: 8
How did you modify steps per mm? I change the defaults settings and the machine type but nothing changes at the machine. The instructions on Github reference a MPCNC build but there isnt one in the defaults.h file.
I’ve already got a big printer and I’ve used GRBL for a laser burner before. GRBL is nice and Chilipeppr is a great interface compared to what I was using for GRBL previously. I wish i saw GRBLweb before I got started today, I still might try it.
What am I missing to change the steps per mm?
PS, anyone seen a pendant hookup for GRBL?ScottParticipantMarch 25, 2016 at 3:57 pmPost count: 8
I figured out how to edit the settings through the serial interface.JeffParticipantApril 8, 2016 at 6:13 amPost count: 157
I’ve been thinking really hard about buying one of these, which will only run grbl, AFAIK.
Then on the pi, you could run bCNC, OctoPrint (if it works with grbl, IDK yet), or this simple web interface: https://github.com/Protoneer/Raspberry-Pi-CNC
Yeah, I’m going to get one, and I’ll let you know how it goes mid-May when it finally arrives 🙂 . My goal would be octoprint, hopefully without doing a large fork like the previous octoprint cnc stuff.
