Hi, I recently bought a Modix Big-40 that has a Duet3D board.
Here are the specs from the WebControl:
Board: Duet WiFi 1.02 or later
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 2.05.1 (2020-02-09b1)
I'm having issues with ringing/ghosting in my test prints. I tried tightening the belts, I tried loosening them, nothing made a real difference. I read that I could try enabling the jerk/acceleration control in the Cura slicer but I'm lost on how to set the values.
The manufacturer has a short tutorial on how to setup the printer in Cura, but that tutorial doesn't say, that I should change the GCode flavor from the default Marlin to RepRap. Which is the first thing that confused me, since this is a RepRap printer?
The second thing are the jerk/accel values. The printer has a config file that has some max values already set:
M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation
M92 X100.00 Y100.00 Z2000.00 E418.500 ; Set steps per mm
M566 X240 Y360 Z30.00 E120.00 P1 ; Set maximum instantaneous speed changes (mm/min)
M203 X9000.00 Y9000.00 Z360.00 E1200.00 ; Set maximum speeds (mm/min)
M201 X1000.00 Y1000.00 Z120.00 E250.00 ; Set accelerations (mm/s^2)
M204 P500 T1000 ; Set print and travel accelerations (mm/s^2)
M906 X1800.00 Y1800.00 Z1800.00 E1000.00 I40 ; Set motor currents (mA) and motor idle factor in per cent
M84 S60 X Y E0 ; Set idle timeout - one minute
What GCode flavor should I use in Cura? What jerk/accel values should I set? Will that even make any difference, since the config already has some values? I also noticed that the printing time is always significantly longer than what the slicer estimates.
I'm absolutely new to all of this, so I would greatly appreciate any help and advice on this matter.
