Re: Need desperate help with tmc2130 :(

Hi Anthony,

A value like "0xFF:FF:FF:FF" suggests a connection issue. Look at wiring, solder, etc.

Re: Need desperate help with tmc2130 :(

Hi Anthony, My first guess is that your currents may not be set optimally for the drivers. Try "M906 X700 Y700 Z700 E700" to set the mA for all four drivers. THEN, reset the EEPROM with "M500". For some reason, Marlin has difficulty setting those values after flashing the firmware. Adjust the "700" ...

Re: Gaps between perimeter and top solid infill

Hi Jan, Looks a little better, but I still see the gap. A nozzle can print lines much smaller than the hole diameter. For example, I usually print with a 0.4mm nozzle at 0.1mm. The point I was trying to make was that the shell thickness should be divisible by the line width. If it isn't, the slicer ...

Re: Gaps between perimeter and top solid infill

Hi Jan, Line width of 0.48 is a little unusual. Is there a reason you did not stick with 0.4? In addition, what have you set your outer wall thickness to? It is possible to create a setup that can't be followed because the math doesn't work (E.G.: how do I create a 0.8 thick wall if my line setting ...

Re: Unpredicatable thermal runaway on my CR10 S5

Hi Riccardo, Welcome to the forum. Dumb question: is the printer actually reporting a thermal shutdown, or is it suddenly freezing during a print. What you may be experiencing is the stepper drivers overheating, which could explain why the printer is fine with the heat on and standing still. If you ...

Re: How do I insert GCODE filament retract?

Hi Tanner,

Try this:
G92 E0; set extruder value back to 0
G1 E-1 F900; retract 1mm

There definitely is a retract on z hop in Cura, but I'm not near my machine to point it out.

Re: Terrible printing with DaVinci 1.0a modified

Hi yoprogramo, Welcome to the forum. I suspect there are several adjustments possible to improve your prints. I would start with adjusting your extruder temperature. Drop it by at least 10 degrees. In addition, look into installing a cooling fan (if you haven't already). The plastic needs to cool re...

Re: What nozzle to buy for the Ender 3??

Hi Matt,

Welcome to the forum. The tip should be fine for your application. Technically, you can use a regular brass tip, but it will wear out quickly.

Re: Plotter Y axis problem

Just curious, are you using the rubber roller(s) to move the paper? My experience has been that a spot of grease or any slight misalignment will cause paper to move diagonally.

Re: Extruder problem

Hi Dennis,

You'll have to switch the extruder in firmware, but you have an excellent idea.
