Think i resolved the problem, replaced the Z motor and seems to be working fine now. Recon its time for complete motor replacement from e3d.

Thanks for the help guys.

Hello All

how to best explain....

So recently my printer started misbehaving on homing z.

when i hit home z it starts homing, but for some strange reason the z axis stops about 0.5 above where 0 should be. I now literally scrapped all the files on the SD card and deployed it all from scratch. Its causing me to get inconstant levels when i was homing z. I have removed the z-probe and now only have end stops (low end) configured. Printer still stopping @ what it thinks is 0 and not even triggering the end stop by about 0.5mm.

Is there a way to clear any settings on the board and resetting it to factory defaults. I want to get the end stops working again, the probe has been problematic.

My Config now.

Funny you say this, ive got a CR10 and im getting the exact same problem. variation is almost a whole 0.1 on some probes.

So as a test ive turned the probe off and using my z endstop. Z doesnt trigger cause the printer thinks that z0 is about 0.5 above the z endstop.

@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.

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.

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.

@Phaedrux said in Cura 4.2.1 Config help:

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?
https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe

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.

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

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.

I had the same issue, change your wifi security so that you force only WPA2 PSK, dont use mixed mode. You can then use 2 and 5G without any issues.

Its not pretty

4000 steps per millimetre on Z looks like an order of magnitude too high...

Aaaahh yes that should be 400. My fat fingers again. Will fix and test.

Morning, ok so changed the speed and removed the rim. This time is printed but the layers where way to far apart leading me to the conclusion that my Z steps are way off.

M203 X6000.00 Y6000.00 Z180.00 E1200.00 ; set maximum speeds (mm/min)
Your Z axis is limited to 180mm/min (3mm/s), which I think is the stock setting; my Cartesian machine (though dual Z motors) is set the same, and your other motor settings are stock. It may be that you need to test if it can actually do these speeds; it's possible there's more weight on the Z axis, so it actually has to be lower. Or, as you've got 4000 steps per mm (0.5mm pitch on your Z leadscrew, I think), at full speed the motor has to do 6 revolutions per second to move 3mm; it may just not physically be able to do this.

Try sending G1 Z10 F180 then G1 Z-10 F180 to check movement. If you do this at Z=0, you should be able to see if it returns to the same place. If it doesn't, try lowering the feedrate from F180 until it does move reliably.

In Cura, the Z Hop speed is set to 10mm/s, which my delta can do, but my Cartesian machine definitely can't! But the config.g setting will limit it to 3mm/s. I don't usually have Z Hop turned on on my Cartesian printer, as the slow Z movement can cause as many, though different, printing problems as having it switched off.

If this doesn't help, can you upload the gcode as @Danal suggested, then we can see what it's actually doing during a print.

Ian

Super, ill try drop the speed and also removing z hop.

I had the exact same. so this is what i had to do to fix this.

Check your wifi security on your router. duet doesnt seem to like multi mode authentication. Set your router to WPA2-PSK and your problem should be resolved. It wont drop off and the browser will work fine.
