X and Y shift during printing.

Which firmware version are you using? If it's below 2.02 stable release then please upgrade it. Some older firmware versions left the drivers run in stealthChop mode by default even at high speeds, and skipped steps are much more likely when using stealthChop.

Veti

also there was a bug with the time keeping constant on longer prints below 2.02 which would cause layer shifts after the printer being on for a long time.

Let us know if it fixes the problem. I can't remember whether the change to the stealthChop settings was made before or after 2.03RC3.

Ignore the fan issue, it was a ID10T error.
I left something in the End gcode section.....Sorry

PaulHew

Fan issue is not a ID10T problem.
I have just printed something again and the tool fan was running slow again.
Checked the GCode file for M106's and it only references the Part fan as far as I can see.
[0_1557774592616_CE3_Mk6_-CR-10-GT2-X_Tensioner-_Body.gcode
This is the file if someone would be good enough to have a look to make sure I am not going mad!

@paulhew, Part Fan == Tool Fan. It's the fan used to cool the print, mounted on the tool. The hot end heatsink fan is different.

PaulHew

My Bad, I thought the tool fan referend to the hotend fan
Hotend fan is having this issue. It is controlled by the duet gcode.

This morning I have been testing the hotend and every time it runs at full speed, after a heating and cooling cycle.

Code responsible
M106 P1 S1 I0 F500 H1 T40
Do I need the F parameter? I only need it on or off. I know its default is 250 if it is omitted.

if that line is in your config.g then the fan will turn when the hotend reaches 40 degrees and turn off when below. there is no need to control it via the g code.

Normal should be around 75% if the current of the steppers.
see https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Rated_current

Isn't that just to keep the temp of the steppers down to avoid printed mounts going soft? Don't think the Ender 3 uses printed parts on the motor mounts.

You don't need the F parameter. The fan should turn fully on when the indicated hot end temperature rises above 40C and off when it falls below 40C.
