SOLVED!
(I think, at least my last 3 hour print was flawless)

Motor currents were set as...
M906 X800 Y1100 Z1400 E650 I30

Stepper specs show max curr/coil is 2amps. So I bumped the current up to 1.5 (M906 Y1500) amps and gave it a try.

Seems to have solved the problem. So this brings up another question...

Q. Just because the motor is rated at 2 amps, in order to be conservative, how does one decide upon the best/optimal current setting to use?

Thank you Phaedrux, I'll try those numbers or something close.

Here is a picture of my extruder/head. It currently has a .6mm nozzle.

@exerqtor
I knew that and, wasn't really serious when I posted the part about M150. Problem is, there is no loop feature (that I know of) in G code so that a light can be made to blink until the operator comes and notices. Just one of those little things that would be icing on the cake but not really needed.

Yes there is a loop facility. https://docs.duet3d.com/en/User_manual/Reference/Gcode_meta_commands

@Cj110109 it looks like the OP dis a great job using the Duet 3 6HC however in checking out the config the max current they are using for the motors in 1.2A and they are using 4 (single extruder) so it looks like a mini5+ would be able to do the job:

You also have expandability within that to keep the second extruder if you wanted to. I cant comment on the hardware elements of the upgrade and how much work that was.

Frederick, per your previous post (and my response) I already spent considerable time tweaking M566 & M201. Nothing seemed to make any difference. Thanks though.

It's hard to remember what I have responded to and what I have yet to respond to.

Sorry about that.

It should have been able to silence it completely. I do not understand why it couldn't.

@brs said in Moving print head out of the way:

Q: When, using G91 and G1 Z50, if the bed is already down less than 50mm from the endstop will Duet respect the configured geometry or will it try to grind past the end stop?

If include a M564 S1, as the first command, it will insure that axis limits are respected.

This way you can use your code safely without worries.

@phaedrux

For some reason the Mesh was working today when I first started DWC. I had HOMEd everything but did not do a z-probe. Your question did get me to realize the mismatch of software.

RRF for Duet 3 MB6HC 3.4.0 (2022-03-15)
<just now upgraded to 3.4.1>

Duet Web Control 3.4.1

Everything is figured out and working. What confused me was understanding the M557 wants locations of the probe not the head. I had been giving it head locations and making calculations to be sure the probe remained on the build plate. This bit of information is not clear on the RRF Config Tool.

Thanks

@bubblevisor, if yo will buy from a repuatable vendor or manufacturer, you may find safety information you can trust. E.g. https://www.mcmaster.com/insulation/insulation-type~sheet-strip/heat-reflecting-air-bubble-duct-insulation-sheets/

You can remove the M574 Z2 S2

Yup! That did it. Thnx.
