Currently flat out with work, but here are my VZBot AWD config files. Printer printing beautifully. Maybe this will shed some light.

printer.cfg 41.65 kB · 0 downloads beacon.cfg 1.21 kB · 0 downloads macros.cfg 25.49 kB · 0 downloads

Thanks mate.

I have my old config files for when it had the Mellow Super 8 fitted. It just doesn't seem to like the Kraken mainboard.

I'll take a look your files and see if anything jumps out at me.

I think I've got it now. 

It appears that my old brain doesn't work correctly when faced with too many variables.

The rear of the printer faces into the room, laptop faces into the room but 180 degs away from the printer, the printer motor layout diagram looks front to rear, etc.

Anyway, I deleted the stepper motor sections from my printer.cfg and then addressed each motor separately and didn't move on to the next stepper until everything was working and going in the correct directions.

A quick update.

All is well and the Vz is running smoothly, and with a 0.8mm nozzle it fair lays down some plastic.

I just have to develop a better mount for the SHT36 and install the RSCS. I tried printing a Temp Tower in PLA, the 0.8mm nozzle puts out some much filament that the CPAP cannot cool it quick enough.

I get back on it when I return from Italy in 2 weeks.

i was doing a bit of a clean up and found this lower right front.

It looks like muggins here forgot the thread locking compound.

It took quite a bit of work to get to that screw (locking compound now applied):

So, I've now got my SHT36 v3 mount done.

I am still working on the repositioning of the CPAP tube intake. I was having problems with the CPAP Tube, the internal thin tubing/sleeve was collapsing and restricting airflow. I'm now running it horizontally from toolhead to rear panel. It's also supported by a length of stainless TIG wire.

 

Thanks to @GalvanicGlaze for the bowden tube support mod.

Looking really good @TitusADuxass 

I powered mine on this morning for the first time in 7 weeks. I have to update my RatRig (I'll make a post) this week, then I will design a side mounted drag chain setup for the VZ. I have grown to hate the umbilical situation on that printer. Need something better.

I'm also having issues with the bed heater. I set the bed to print temp and the bed heats up and right when it gets to the set temp, the temp on the heater drops and the printer faults. It could be the internal thermistor is bad or could be a SSR issue. I get around the error by restarting the printer. Works for now but needs fixing.

In case anyone is interested here is my SHT36 v36 mount, it should work on other SHT36 variants.

Big tip of the day - do NOT plug the Hotend Thermistor in to the fan socket (and the HE fan into the thermistor socket) on the SHT36!

Now I've got to wait on a new SHT36.

I really don't like the umbilical either, never thought about drag chains though.

I'll be watching your posts.

Yup, it's time to dive into printers again. Work has been keeping me super busy.

Seems we're all in the same boat here
