LDO-36STH20-1004AHG (XH) getting hot
Hello folks,
I have an Orbiter 2 with LDO-36STH20-1004AHG (XH) steper motor and a mosquito magnum hotend. When I built the vcore3 first I used the normal orbiter.cfg but got a really low flowrate. So I changed it to the [include RatOS/extruders/orbiter-1004.cfg]. I have no overrides for steppers done yet.
Now the stepper is getting really hot over time, but flowrate is perfect.
It is getting hot too, when I don´t extrude filament. So hot, it is barely touchable. Is this normal?
Newest observation is a clogged hotend with PLA (printed at 200°C) at the top/entry of the hotend. After inspection I noticed an slightly angled cut PTFE Tube, my fault. All the last prints were under 2h (worked fine), but now it was 3h. It got clogged after I had a print section with only 10mm/s printspeed because of lack of cooling. Maybe the filament was getting warm and flexible while passing the extruder and then it was compressed in the gap and cooled down --> clogged hotend.
What do you think?
How can I avoid this problem in the future.
Before I start printing again I want to know

I run 4 sherpas across many printers. I know its not exactly the Orbiter but maybe I can give you a bit of insight. The motor does get too hot to the touch during normal operation. I print a lot of ABS, and on my DOOMCUBES, I am getting 75C chamber temps. Again, no issues on the motor. I would doublecheck your currents and make sure they are appropriate for the motor though. Less current=less heat as the expense of pushing power.

are you fix this problem? ı have same problem...

You may also want to make sure that your fan is cooling the magnum well too
thank you very much!
every performs perfectly with a straight cutted ptfe tube now 🙂
have a nice day!
