Welcome to the SeeMeCNC Community

I have a Rostock Max v2 that has been upgraded with the HE280, dual EZR Struders, and the bowden splitter. I never got around to getting dual extrusion working, but last I was printing with it, it was printing and calibrating well. My time is just spoken for elsewhere for the foreseeable future. I'm...

With lots of kreagar's help, some things we now know about implementing this using Repetier and MatterControl: MatterControl does not support M83, and M83 will make crazy things happen if you try to use it in MC's custom gcode, so the M83 part has to go in the firmware. It doesn't support switching ...

For anyone's future quick reference, here is where the Y axis needs to be inverted in the firmware: // ###### Inverting Axis Settings #if PRINTER == 1 || PRINTER == 2 || PRINTER ==4 #define INVERT_X_DIR 1 #define INVERT_Y_DIR 0 #define INVERT_Z_DIR 1 #elif PRINTER == 3 #define INVERT_X_DIR 0 #define...

Well there you go! I have apparently never tried to run the extruder while the hot end was cold. Makes sense. I actually started out indicating the machine as a V3 in the firmware, but it gave me the crazy arms with the inverted Y axis. I hadn't seen anyone mentioning that, so I just figured, "...

I could use some help. I've assembled and installed the new HE280 on my V2 and I can heat the nozzle and bed, home towers, and move on all axes in MatterControl's controls correctly, but I cannot control the stepper motor, and if I run the "V3probing" G Code, the machine does nothing at al...

I've slowly pushed my way up to printing PLA at a max speed of 120mm/s, with things like the first and top layers at various slower speeds depending on the print, all at 235C, and I see no reason not to push for faster. The only time I've seemed to be pushing against limits is when I have to dial th...

I watched it more carefully and caught it in the act of failing, and, yup, as soon as it starts going full speed, it goes off the rails and starts doing naughty things with its filament.

Is there a cure for this other than going more slowly?

Video of behavior: https://www.youtube.com/watch?v=RlIEp4mXtAU I'm attempting to print a very full bed of individual pieces here. You may or may not be able to see in the video that I'm really pushing the boundaries of the print area, with even a couple of corners going outside the outer circle on t...

Holy crap, it was the SD card. I put it in just because I had it even though I print from a MatterControl Touch. I may never have even remembered I had one in there.

Thanks for the isolation procedure anyway, but thanks even more for the easy fix!

So, I got my machine assembled without too many hitches, it had been making decent prints and I was chipping away at calibrations while I built the table it is to live on. I got the table built, moved the machine across the room to the table, and now when I turn it on it continuously cycles between ...
