Hi Kevin.
I did get another shutdown event but only after cancelling a print and trying to home.
I have klippy log but it is too big to upload even compressed.
Do you want me to get the start and last bits of the log file?

Hi Kevin.
I updated to latest version and ran about 4 or 5 prints off with no re-occurrence of the issue at the end of print. I have not had a chance to test maximum speed yet as I have only just converted to 24v but will hopefully at the weekend.
Regards
Chapelhill.

Hi Kevin.
Full compressed Klippy log attached:
I have been doing some more printing and with same end script it does not always have the problem and I have only experienced it at the end.
Hope that helps.

Hi Kevin.
I updated code today and have been using the stepper drivers in 32x micro stepping for x, y and extruder, still using z stepper on 16x but I think the calculation for the step distance on Z might still be causing a problem (1.5mm pitch.) The print worked completely normal except when it was probably executing the print end script and the Firmware crashed. It could be an error in my endi

Hi Mark.
I tested the code for the variable overflow in compression on my corexy at the weekend and did not manage to get any further incidents of the firmware stopping using my theoretical X,y and z step size. When I get some more time I will try the 128 microstepping which was the worst case last time to give a more thorough test.
Thanks
Regards

Hi Kevin.
Thanks very much for the quick response and updates, I will have a go as soon as my current print has finished and flash back Klipper onto the Arduino.
Regards
Chapelhill.

Hi Kevin.
How do we upgrade our package? I have seen a number of updates have been posted recently.
Have been trying to do some actual printer rather than test prints, but I am hitting the issue of firmware restart on X and Y axis which is only with 3 decimal places (0.0125 and also with 0.0124) and I will lose quite a bit of accuracy to go to two decimal places.
My drivers were supposed to be

The loosing steps on the extruder sounds like the issue, I didn't think about that. I will try different pressure advance settings on the troublesome model at the weekend. I will also need to check maximum extrude speed and acceleration recommendations as I may have them too high. I have an alloy 60 tooth belt driven wheel with 20 tooth stepper wheel . I had the impression of the hammer noise in

I followed instructions as per pressure advance document in increments of 0.05 and could not really see any difference in quality on corners of box but it is a new build where I still have some learning to do so left it at the final setting which I think was 0.2.
On subsequent prints I noticed on the short stroke diagonal in-fill sections on you could see the extruder going further and further

Hi all.
I tried pressure advance on my corexy with it set to 0.20 ( I think that was default) but time parameter at 0. I have a geared extruder and over regions with lots of zig zig my extruder was going net further and further backwards leaving small regions with no filament. This was the object

It also sounded like it was hammering the extruder and pushed out PTFE from fitting but th

Hi all.
Following on from other successes, I thought I would try this on my Hypercube corexy, but being newer my progress was somewhat slower.
I am using cheap as you like Ramps 1.4 with A4988 with steps set to 16x with Arduino MEGA2560 and a Pi3 and Z axis with Trapezoidal threaded spindle RPTS right TR 8x1,5.
I struggled to organise the x and y config so that X and y moved in correct directio
