Hello I’m trying to get this BenchTop PRO back up and running at my institution after not having an operator for a while.
I needed to retire the old computer it was installed on (Core2 DUO) Running windows 7 upgraded to 10 imaged the old drive to a new one and migrated to newer hardware.
I have followed all of the set up instructions here
https://www.avidcnc.com/support/instructions/archived/software/softwareSetup/
We are using the Ethernet Smooth Stepper
Updated to the Latest Version of Mach3 available Version R3.043.066
A couple of things I’ve noticed while setting this up, the pins are reversed for the x-- x++ and y-- y++ so the – limits and home were in the rear right corner.
It would properly home there.
If I swap the pins under config → Ports and pins they properly trigger under diagnostics, I carefully position the spindle to the forward left position where the x/y – and x/y home are lighted up.
I then go to settings Reset Interp, and zero x and y in machine coordinates, then hit to DRO to set zero to the forward left position. Z appears to home to 8" fine; however, if I hit REF ALL HOME It homes the Z and gives the green homed outline, then it starts driving the Y toward zero, then hits the bumper and continues to try moving until I escape the homing sequence.
WTF is going on?
The only weird thing I’ve found so far is the default xml file I’m using
“BTP2424_800_23375_SPINDLE_19.2.1.xml” From here
https://www.avidcnc.com/getfile.php?cat=Mach3XML.19_2_1&file=BTP2424_800_23375_SPINDLE_19.2.1.xml
The value:
<M2RefHome>40640</M2RefHome>
seems really weird but changing it to 0 doesn’t help.
I know a little about data types and if that value is assigned to something like an int16_t value that will end up being some negative number which is no bueno and very awkwardly stated.
If I enable Soft Limits I can jog right up to the forward left position with the appropriate slow down, although it never gives me a green homed indication.
Why would REF ALL HOME, ignore soft limits and ignore the home sensor triggered and continue to attempt to drive off the table?
And why is there no way to view what coordinate Mach 3 thinks it’s trying to go to for home?
Is there an easy way to fix this? Going to Mach 4 is not an option right now as we must get a grant to purchase any software licenses and is a very slow time consuming process.
Any help would be appreciated!!!
