Over the past several years I have had different 3D printers and controllers, Melzi, MKS... I have used Marlin and repetier firmware, all with success and generally I have always been able to print what I needed.

My latest is a TronXY X5SA Pro, I really like the mechanics of this printer, it's solid and works well. The stock controller was not terrible, but I wanted better ( to me anyway ). I replaced the controller with a Duet WiFi and 5" paneldue display.

For the most part the new setup just worked. Had to change my way of thinking from what I did in the past, but it was not a big deal.

For what issues I did have questions about, folks on this forum provided quick and useful help and made things that much easier.

So thanks to the developers of this hardware and firmware and to the folks that helped me and the many others I see in the forum.

I did think of that, but I notice my MCU just never gets hot and I think it is too far removed from the drivers.

@fcwilt

If I ever open up my controller case, it would not be horrible to glue a thermistor to one of the drivers.

Thanks

OK, I think I got it, was not hard to figure out. Seems M584 is order driven. I just changed Z2:4 to Z4:2 and it seem to be working.

The macro sets the Z height offset which I do before every printing run.

Removing that line you pointed out fixed the issue.

The routine does not use the probe to measure. In the routine, I move the Z axis to get the nozzle to table clearance I want and set that to be the new Z0 position. I do find this changes based on bed temperature used. I find the probe OK but since doing this Z offset before every print, I have very few print failures cause by poor first layer.

Before a print I like to,

Bring bed to temperature
Do bed level
Do mesh level
Bring nozzle to temperature
Do Z offset

Then print

These steps have given me very good and repeatable results. Do I have to do this, maybe not, but it takes no time and the results are consistent.

Just habit, different bed temperature, different nozzle temperature.
Get the nozzle Z height perfect every time. Take less that 30 seconds.

@Phaedrux

I will look at that, I did not put that there. May be a leftover from a config build script

@Phaedrux

I just confirmed that those file are empty

@Phaedrux

I don't have any I know of, my printer is just a single head

@Phaedrux

I played with this more, it seems to be the tool declaration that causes the issue. If I comment out the T0 line, the zero routine fails because there is no tool selected.

So I put a T0 line in my homeall script, so now I get the same issue when I homeall.

It seems something is going wrong with the tool declaration T0.

Can you run 2 fans, do them in series?

Here are my files.

Thanks

config.g

config-override.g

homeall.g

homex.g

homey.g

homez.g

Well, sounds like I will just leave it at a fixed value ( quiet ) and not worry about it. I have been running it for over a year with the fan off, never had a problem.

Thanks
