@rbjam83 Try a 1.8 deg stepper on your extruder, there is really no advantage to 0.9 here...whereas there arguably would be on X&Y.

Try a different micro step / interpolation setting on E also.

Looks correct to me...although I understand that the later boards have the diode in-built so not strictly necessary to add one there.

Hi.

I'm testing a liquid-cooling solution which came with an adaptor to suit the thread-mount.

Others in the same beta program have fitted the unit no problem, but my half-nut and thread seem different.

The supplied adaptor is M12 x 1.5 , which most other people have found fine.

However, my Duet kit seems to have M12 x 1.0 thread ?

Which is correct and ongoing, do I have a pre-release version or something?

Thanks, Ben

@klcjr89 Thanks, I think I'll go parallel too.

What is the noise like generated by the air pump in use or parts cooling? I guess it runs at a relatively low PWM for this purpose....

@klcjr89 Which of the brushless pumps is best for this application? Series or parallel?

It'll be the same set up as Tevo Little Monster I'm sure. You're right, there's an SSR in the power box. So just connect the 24V bed heater wires from the MKS, onto same points on the Duet board.

The Duet then just controls the SSR (barely any current), bed current continues to flow through the SSR as before.

6 factor calibration - I've set the rod lengths myself as I had the calibration numbers from the labels on the mag-ball arms.

No, i'm using a smart effector so that shouldn't be the issue.

Hi David,

Thanks for the input.

My process (in start g-code) is usually

1. G28 ; home
2. Heat up extruder to printing temp, heat up bed to printing temp.
3. G32 ; (runs bed.g, which does somtehing like 8 perimeter probes and 5 intermediate probes and centre probe)
4. At the end of my bed.g file, I have G29 S1 to load mesh
5. Run purgenozzle.g

So in essence I'm auto calibrating at printing temperatures and printing begins with no homing move between the calibration and the print starting.

Does that sound like I'm doing everything correctly?

I did a big print (first layer 0.15) that took up almost the whole bed (240mm diameter) and was getting very squashed, almost non-existent extrusion on the left side of the bed, and much taller extrusion on the other side (calibration result was 0.039)
