Re: Prusaslicer 2.x

share the gcode CAUTION : My heavily customized start_gcode will crash your M2, because you haven't relocated the Z-axis switch, haven't calibrated Z=0 at the platform surface, and don't put the XY=0 origin in the center of the platform: https://softsolder.com/2015/03/31/makergear-m2-slic3r-start-g...

Re: Prusaslicer 2.x

[PETG mostly It's "PETG exclusively", to the extent that I have exactly one configuration that I use for (almost) everything. I fiddled with the various save / restore options in Slic3r, but never really used them for anything other than a few truly oddball objects that didn't look like my usual br...

Re: Prusaslicer 2.x

save each of the setting groups individually for later use You can save all the current settings with Export → Config and reload them with Import → Config. After you finish tweaking the settings for a particular project, that's a good starting point for something similar. Similarly, you can save / ...

Re: Overhang threads

width of the ramp only needs to be ~ 3 mm Because the threads run perpendicular to the slope of the ramp, you're not ever going to get a sliding-smooth surface, particularly if the matching object is also 3D printed with a matching thread orientation. The central problem is building a slope by sque...

Re: 1st Gen M2 heat bed dead again :(

That little green LED is on Mmmmm, my remembery has failed. I thought there was an LED on the edge of the platform, connected in parallel with the heater power. That's not what you have, alas. Turn the power off, unplug the heater connector at the platform, and measure the heater resistance. If it'...

Re: 1st Gen M2 heat bed dead again :(

original 12v PSU brick's LED is on as well The fundamental problem is the absurdly high current drawn by the 12 V platform heater. All those LEDs show the low-current control path works fine, but I'm reasonably sure the teeny LED on the front of the platform isn't glowing, so the high-current path ...

Re: Strange Z motor move

The five numbers within the curly braces set the current for the X, Y, Z, E1, and E2 motors, in that order.

Change the third 135 to whatever value produces enough torque to lift that aluminum platform. Try 185 first, then 215.

So, for example:

Code: Select all

#define DIGIPOT_MOTOR_CURRENT {135,135,215,135,135}

Re: Strange Z motor move

Any idea? Make sure the Marlin firmware sets a sufficient current for the Z-axis motor. Look for DIGIPOT_MOTOR_CURRENT in either Configuration.h or Configuration_adv.h (which file depends on the Marlin version you're using) and change the Z-axis value as needed. The normal value seems to be 185. Re...

Re: stange Z movement

a short video If you can move the platform smoothly from bottom to top with just finger torque on the leadscrew, then replace the motor. For conclusive proof, remove the four screws holding the Z-axis follower nut to the platform, hold the platform near the top, and home the Z-axis. If the leadscre...

Re: M2 Dual extruder. No power to both extruders

Do they run off the same chip? At least on the RAMBo V1.3, there are two driver chips. Seems unlikely that both blew at the same time. Stranger things have happened, but, at this point, I'd break out the oscilloscope to verify the chips are getting step pulses from the microcontroller. That bifurca...
