Basic Information: Printer Model: Tronxy 500 MCU / Printerboard: Spider V2.2 klippy.log Hello! I have some confusion about setting up the printer. X/Y/Z=0 the nozzle is on mechanical X/Y/Z = 0 I use the [stepper_x] position_endstop: -36 position_min: -36 [stepper_y] position_endstop: -…

Here’s the Printer Test model ( Printer_Test_0_03.zip (10.3 KB)) that I use that matches @Sineos 's suggestion quite well: [printer_test_0_00] It’s five layers, each 0.2mm higher than the last with holes at corners as I found that was the most challenging situation for a Cura generated model. Not…

I have added STL to the allowed extension. One remark: Judging flow on the first 1 to 3 layers can be misleading since you might have effects of the first layer(s) (e.g. too much / too less squish) which will fade out in the following layers. I prefer to judge my “flow quality” after at least 4 la…

Thanx for adding .stls as an allowed extension. Fair enough, I’ve been using this to nail down the first few layers, after which I tend to get very good print quality. Depending on the model and situation, I like to use rafts and this is a good indicator of the quality of the rafts.

perfect, thx! I will do again the hardware calibration of the extruder and then printing the test part.

rotation_distance: 24.96 # BQ gear_ratio: 7:1 # BQ values are different to the last test, do not know why? (10,99) 50mm on Mainsail, are 50mm now on filament traveled OK? anything else to test on the mechanic?

[IMG_3966] Layer is not closed, 0,27mm 0,47mm 0,66mm 0,87mm

tried again with the settings I had bevore: rotation_distance: 10.7 gear_ratio: 7:1 # BQ [IMG_3967] much tooooo much, so the real is somewhere between ?? I do not get the point.

[image] E Steps and ratio? General Discussion Kick out gear_ratio Use rotation_distance = <full_steps_per_rotation> * <microsteps> / <steps_per_mm> = 200*16/932 = 3.433 as rotation_distance Fine tune rotation_distance as per Rotation distance - Klipper documentation …

OK, but its just a dividing value, described in the linked docu. I will kick it out, and recalibrate again.

now I have these values: rotation_distance: 3.54 #gear_ratio: 7:1 # BQ nozzle_diameter: 0.4 filament_diameter: 1.750 test_print is running, looks good, so there must be another influence of gear_ration, not only a division?

Some general settings....?
