The filament cooling fan does not come on, the fan attached to the extruder stepper motor does.
Using microswiss all metal hot end, no insulation around hot end, cooling fan comes on during preheat to keep the warm end below melting point, and heats just fine from the control panel. Btw, using...
Heated bed not being used
When I try to start a print, nozzle temp set at 200, it will heat up to ~193 and stall. Printer will time out. I go in and set nozzle temp to 193, it heats up to 186, printer times out. I'm stumped,...
This thread started out with me asking " why are my steppers burning my fingers? Should they be that hot?" And someone told me to check and see what my Vref's were set to. They were maxed out (118)...
Z40 stayed the same throughout the test , everything else stepped down together. Its printing some really nice parts without failures with the one exception when running everything at Vref=40.
Here is my Vref experiment. I printed the same part with only the Vref value changing. Started at Vref 118, then went to 100, 80, 60, 50, 45 and 40 at which point my part failed to firmly point the...
Hello suds, Under ReplicatorG’s “Machine” menu select the “Onboard Preferences” item. In the resulting window, select the “Homing/VREF” tab? Change the values and then press the “Commit” button....
You are awesome, changed Vref from 118 to 100 and stepper motor is cool to the touch.
Tks
Update, found it, that was easy. Thanks for your help.

I guess it's time to reveal my ignorance, to address the Vref adjustment, is that done via the firmware or a POT on the stepper driver etc? Is this something a novice should attempt?

Is it normal for the extruder stepper motor be too hot to touch? Seems like there should be a thermal break of some sort between the extruder heater and the stepper.
Tks, Roger
