Why did you a dist-upgrade ?

The kernel is a custom kernel (this has been explained in the first thread of the Rpi image thread) and does not come from the debian repos (the kernel sources are from the RPi github repo and contain patches specific to the RPi platform), from memory the debian kernel packages don't have the RPi patches nor support for dymanic device, eg spi, I2C and such.

Save your configs, reinstall and don't do a dist upgrade, there is no need to upgrade the kernel, if you do have stability related issues related to the kernel please make a report in the forum.

Not being to turn off the Rpi could be related to a device tree issue, eg the GPIO that is used is not setup correctly.

Try removing the LIMIT entries from the JOINT_n sections. That should set the value to +/- 1e99 which no machine will ever reach.

I tried G10 L20 P0 A0

This doesn't work. It's resetting the work coords to 0 so the G-code works at first, but continues incrementing A0 indefinitely in machine coords. After about 10 runs, the G-code faulted mid-run, says the next command would move joint 3 past machine limits.

At that point, A has reached 9800 or so, ini limited A to 10,000. I can put in a larger number. but we're just kicking this can down the road.

Can I reset the machine coord value, or is there a way to say the A axis has no limits on how many times it can turn?

My Maho homes off the Heindenhain LS-403 scale index marks. Works the same as homing to a a separate homing switch.

Having ome slight problems here and was looking to see if someone could give me a hand.  I am finishing up a build and the last piece of the puzzle is the spindle and some of the outputs.

I am using a 7i96 that was reused from another machine and was set up for 4 step 1 pwm.  not sure the version of the firmware, but it should not need to be changed.  The computer is a clean install of 2.9 and the original configs from the previous machine doesn't work.  It was made using jt's 7i96 tool and then heavily modified.  so as of right now, I have most everything set up using mesaCT with some generic general values just to make sure that i can move and home each axis. so far so good.  

The spindle is 2.2kw 220v using a huanyang ec01 vfd which takes a 10v pwm signal so i have it ran through a small analog converter from the mesa board.  Now when i try and add the spindle to the config in mesaCT, all of the spindle controls are greyed out even though in options i have it set as 4 step 1 spindle and in axis, there is no spindle option right now. 

also, for some reason i can not get axis to turn on my relays either using mesaCT.  I have them set as mist/flood right now for testing, but i get nothing.  are these some bugs with mesaCT or am i just missing something obvious?  Thanks!

Hi I have the same unit and on the high speed gearing, (up to 4000, I cant get to run below 500RPM. Are you finding that also?
