Microstepping - X:16(on), Y:16(on), Z:16(on), E:16(on)

I have checked and when i send a +5 Z moves 5cm up.

Z4000 for the steps per mm is probably an order of magnitude too high for a CR-10. Z400 is likely the correct value.

Z+5 should only move 5mm.

Shaun

morning

I have checked every measurement now. movement is exact. Layer 1 still seems to be 2mm above.

@Shaun Can you please post the contents of your homing files then?

Your homing files are configured for endstop switch homing and now Z probe homing.

https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_Z_using_a_Z_probe

Instead of this:

G1 S1 Z-405 F1800 ; move Z down stopping at the endstop
G90 ; absolute positioning
G92 Z0 ; set Z to axis minimum (you may want to adjust this)

You need a G30 command to probe the bed.

And your BLTouch command should be updated to this:
M558 P9 H5 F100 T5000 R0.5

And I assume you've gone through this?

Thanks for the feedback, think i figured it all out shortly after updating this.

I want to use my endstop and not the probe which seems to be working just fine.

my issue was that i dont think i hat the hotend touching the bed before starting the calibration. |The result was an offset of 2. i printed the golf marker in rough and super fine without any issues. Will move onto something bigger and update tomorrow.

Shaun

OK found the following which could be contributing to my problems..

When i "Home All" Z doesnt stop by hitting the endstop. it doesnt even trigger the endstop. When i "Home Z" the endstop is hit and triggered.

Silly question, how do i clear any settings saved to the board memory? Ive made so many changes and think starting from 0 would be a good idea.

wilriker

@Shaun Either run M999, push the reset button or power-cycle. In all cases it will reload config.g discarding all changes made since the last start.

Shaun

@wilriker Thanks. Cant seem to get z to move down and trigger the endstop. I have loaded a clean config.g file. Its as if a setting is telling z to stop when i gets to 0 which isnt the high of the endstop.

Can you explain what you mean by that?
