Title: Reset required after G31 probing moves?
Post by: lesspaul on June 14, 2018, 03:10:32 PM

I am seeing something that seems unusual to this Mach4 newbie. I just got done writing my second script -- tool zero probing -- and found a strange behavior. Following a G31 probing move the MDI is disabled.  Test code:

Code: [Select]

mc.mcCntlGcodeExecuteWait(0,"G91 G31 Z-2.0 F5.0)
however, if I press [Reset] or add mc.mcCntlReset(0) to the script all is well and the MDI works as expected.

Code: [Select]

mc.mcCntlGcodeExecuteWait(0,"G91 G31 Z-2.0 F5.0)
mc.mcCntlReset(0)
I am using the most recent release version of Mach4 (4.2.0.3804) and Ethernet Smoothstepper with firmware #220.

So my questions are: Is this normal? And if not, which is the most likely culprit, something I did, Mach4 or ESS?

For completeness sake, here is my entire tool zero script:

Code: [Select]

local inst = mc.mcGetInstance();

local TouchPlate = 0.622 -- Thickness of touchplate above material
local SlowProbeRate = 0.7  -- IPM
local FastProbeRate = 5.0  -- IPM
local JogRate = 60
local Pos

mc.mcCntlSetLastError(inst, "Probing for Z Zero . . .")
wx.wxMessageBox("Ensure touch plate properly positioned and connected, then press ENTER.")

mc.mcCntlGcodeExecuteWait(inst,"G91 G31 Z-2.0 F".. FastProbeRate)  -- Probe TouchPlate at FastProbeRate
mc.mcCntlGcodeExecuteWait(inst,"G91     Z0.05  F".. JogRate)        -- Retract
mc.mcCntlGcodeExecuteWait(inst,"G91 G31 Z-0.07 F".. SlowProbeRate)  -- Probe TouchPlate at at SlowProbeRate

Pos = mc.mcAxisGetProbePos(inst, mc.Z_AXIS, 0)  -- Get Touch Position (work coordinates)

mc.mcCntlGcodeExecuteWait(inst,"G90 Z".. Pos .. " F".. SlowProbeRate) -- Move back to touch point in case of overshoot
mc.mcAxisSetPos(inst, mc.Z_AXIS, TouchPlate) -- set DRO to height of touchplate
mc.mcCntlGcodeExecuteWait(inst,"G91 Z1.0 F".. JogRate)        -- Retract

wx.wxMessageBox("Z Zero Set. Remove touch plate and press Enter")
mc.mcCntlSetLastError(inst, "Z Zero set")

mc.mcCntlReset(0)

Did you ever determine the root cause of this?  I'm running into the same issue and would like to not have to click reset between most every move.

I think you need to change the setting under the ess config spindle there is a check box to toggle this issue.

Thanks for your reply Gary but unfortunately I'm using a UC-100, Mach4 latest build and Windows 10.  An ESS is in my near future however.
