Cura 4.2.1 Config help

Shaun

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.

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

With the sole exception that he is using a M5 threaded rod. But yes, more common these days are TR8x8 lead-screws which have 400 steps/mm.

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

droftarts

Funnily enough I use M5 rod on mine, so Z4000 looked right to me! I think I remember thinking "I wonder what a CR10 has for leadscrews?" at the time I wrote it, but then forgot!

@Shaun You can probably turn the speeds for Z back up now, as the motor will probably be able to lift the Z much faster now, assuming it has enough torque to move the Z that fast. But do test it at it's maximum speed.

@Shaun That just gives the minimum and maximum coordinates this print will reach for every axes. In this case your part is 10mm high according to these comments.

And there I was feeling silly after wilriker's comment, but I was fairly sure that in all the pictures I'd seen of the CR10, it was using a lead screw and not a threaded rod.

I feel vindicated!

Hope it fixes your Z height problem.

Ooops! Besides being the wise-guy that I am sometimes (=most of the time ) I actually wanted to express that I think you were right. Sorry I did not bring that across.

Still struggling to get this resolved, any other ideas i could try? Thinking i should scrap Cura and try something else to see if it resolves the problem.

Hi,
Here’s a link to “CCR10_Golf_Green_Marker.gcode” in my Dropbox:

burtoogle

Thanks for the gcode file. I can't immediately see any obvious issues with it. What exactly is the problem you are having?

Shaun

Does look like a problem with scaling in Z. The gcode looks OK.

droftarts

@Shaun This gcode should only be 10mm high, but your axis looks like it has moved a lot further than that.
Can you send these commands and report the output from the console: M92 and M350
This should report the steps per mm and microstepping in use.
Can you also post your current config.g and, because there's an M501 at the end, your current config-override.g
Measuring how far a Z movement of 10mm moves the axis might be helpful too, as well as a picture of your Z rod with a ruler next to it for scale.

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.

morning

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