Mach4 General Discussion / Re: Simple Lua question

Your mcCntlGCodeExecuteWait uses inst as a parameter, check to make sure that it is not nil at that point.

I would throw these lines in right before the first

prb.SingleSurfY(ypos, work)

to check to make sure that these values were valid:

if prb==nil then
  wx.wxMessageBox("prb is nil")

if inst==nil then
  wx.wxMessageBox("inst is nil")

General Mach Discussion / Re: creating a second MACH3 profile?
« on: March 29, 2017, 11:48:15 AM »
Start Mach3 loader, choose create profile.  Highlight your existing profile, enter a new name for the duplicate profile eg. AccellMill.

You can then change the motor tuning to whatever you want.  All the other settings, ports, pins, etc. are copied.

Modifying the machine.ini file for the [Log Window] entry to a screen position like 5,5 brings the window into view.  Anyone with less than 1725 pixels in width will not be able to get to the window unless they modify the ini.

Thanks Brett

Thanks Craig,

I was supposed to send a log file demonstrating lathe's miss handling of G31 calls but can't send a log file that doesn't exist.  Seems like mach4 lathe is once again the red headed step sister like mach3 turn.  I guess I have to open another support ticket.

Can anyone tell me whether they can replicate this problem.  Just load mach4lathe profile and then go to 'Diagnostics->Logging...' and see if you get the standard logging window or a window that has nothing yet has a taskbar presence.  I have it on two machines and get the same invisible window.  If I load Mach4mill I get the standard logging window.

I have re-installed on one of those machines both using ver 3233.

All of the above is valuable. If your Z axis is slightly non perpendicular to either the X or Y axis ( not trammed to the bed)you will see exactly what you are referring to, small step like  line on one side of the pocket.

A poor man's way to check is to take a coat hanger, cut it and bend it so that one end can fit in the collett, extend it several inches laterally and then have the other end point to the bed. Lower the Z so that it just touches the bed and then spin it slowly by hand. 180 degrees. If it is not trammed  it will lift or dig in on direction.

post your gcode and micrometer your bit

There is no way for us to tell you what is your problem.  Each machine, even of the same model, may have different characteristics due to shipping, assembly or usage. 

Most likely reasons are binding on axis, tool not being held tightly (debris in collet prevents full closure), motors too small for load, loose coupling on screw.  Then you get to too much acceleration or too fast for the stepper to handle it.  No magic formulas here, sorry.

Search for motor tuning acceleration or missing steps and you will get a plethora of possibilities.
