My thought was that they may be writing to OEMDRO2000, 2001,2002, ...

But maybe their notes are completely wrong.

you seem to be right, missed the post with the Changelog notes.
Looks like they are writing UserDro 2000...

from Mach3Mill_1.84 doc
chapter 10.7.12 Straight Probe – G31

description:

After successful probing, parameters 2000 to 2005 will be set to the coordinates of the
location of the controlled point at the time the probe tripped and a triplet giving X, Y and Z
at the trip will be written to the triplet file if it has been opened by the M40
macro/OpenDigFile() function (q.v.)


example code:


N010 (probe to find center and diameter of circular hole)
N020 (This program will not run as given here. You have to)
N030 (insert numbers in place of <description of number>.)
N040 (Delete lines N020, N030, and N040 when you do that.)
N050 G0 Z <Z-value of retracted position> F <feed rate>
N060 #1001=<nominal X-value of hole center>
N070 #1002=<nominal Y-value of hole center>
N080 #1003=<some Z-value inside the hole>
N090 #1004=<probe tip radius>
N100 #1005=[<nominal hole diameter>/2.0 - #1004]
N110 G0 X#1001 Y#1002 (move above nominal hole center)
N120 G0 Z#1003 (move into hole - to be cautious, substitute G1 for G0 here)
N130 G31 X[#1001 + #1005] (probe +X side of hole)
N140 #1011=#2000 (save results)
N150 G0 X#1001 Y#1002 (back to center of hole)
N160 G31 X[#1001 - #1005] (probe -X side of hole)
N170 #1021=[[#1011 + #2000] / 2.0] (find pretty good X-value of hole center)
N180 G0 X#1021 Y#1002 (back to center of hole)
N190 G31 Y[#1002 + #1005] (probe +Y side of hole)
N200 #1012=#2001 (save results)
N210 G0 X#1021 Y#1002 (back to center of hole)
N220 G31 Y[#1002 - #1005] (probe -Y side of hole)
N230 #1022=[[#1012 + #2001] / 2.0] (find very good Y-value of hole center)
N240 #1014=[#1012 - #2001 + [2 * #1004]] (find hole diameter in Y-direction)
N250 G0 X#1021 Y#1022 (back to center of hole)
N260 G31 X[#1021 + #1005] (probe +X side of hole)
N270 #1031=#2000 (save results)
N280 G0 X#1021 Y#1022 (back to center of hole)
N290 G31 X[#1021 - #1005] (probe -X side of hole)
N300 #1041=[[#1031 + #2000] / 2.0] (find very good X-value of hole center)
N310 #1024=[#1031 - #2000 + [2 * #1004]] (find hole diameter in X-direction)
N320 #1034=[[#1014 + #1024] / 2.0] (find average hole diameter)
N330 #1035=[#1024 - #1014] (find difference in hole diameters)
N340 G0 X#1041 Y#1022 (back to center of hole)
N350 M2 (that's all, folks)


as written, a good Motion Controller or PP machine will have the exact result of G31 in
uservars 2000...2002

I moved the " mark from in front of the G00 to In front of the X and now the machine works as it should.

imho by doing this, you should see a scripter Compiler error in the Status line, and the M6End macro
will not be executed at all. -> so no move

there is a big difference between GetVar(2000...2002) and GetOEMDro(2000...2002)

a good Motion controler uses the Variables 2000.2002 to strore the axis values exactly when
the probe was hit (allmost realtime), nothing will happen with OEMDro 2000...2002

V2.38.4 2015.7.8
1. add probe variable 2000-2003,but it maybe still could not compatible with mach3 screen 2010.
if you want to probe with screen 2010, please replace the GetVar(2002) with getoemdro(802),
GetVar(2001) with getoemdro(801),GetVar(2000) with getoemdro(800).

if you use OEMDro 800...802 you will allways get the value from the probe hit + overtravel depending
on the time the axis Needs to stop.

This will home at the homing speed in Config>Homing/Limits, then home again at 1/10 the speed.

So if you set the Homing speed at 50%, it will home at 50% first, then 5%.

DoButton(24)
DoButton(23)
DoButton(22)
While IsMoving()
Wend
SetParam("XRefPer", GetParam("XRefPer")/10)
SetParam("YRefPer", GetParam("YRefPer")/10)
SetParam("ZRefPer", GetParam("ZRefPer")/10)
DoButton(24)
DoButton(23)
DoButton(22)
While IsMoving()
Wend
SetParam("XRefPer", GetParam("XRefPer")*10)
SetParam("YRefPer", GetParam("YRefPer")*10)
SetParam("ZRefPer", GetParam("ZRefPer")*10)

sometimes i wonder why a searchfunction has been invented

General Mach Discussion / Re: UC400ETH soft limit problem

« on: April 23, 2019, 02:28:05 AM »

I don't think this is a port/pin issue or even a board issue. It is the way the UC400ETH handles software limits. So i guess i'm saying i think this is a plugin issue.

1. If your port 2 of UC400ETH is unconnected you need to pull up or pull down all the input pins (see attached).
It is TTL logic NECESSITY.
2. If you think it is a plugin issue, connect your PC to the internet (may require an Ethernet switch) and the plugin should automatically update to newer version.
People on CNCZONE already had false triggering of limit switches with UC400ETH even in 2017. So if CNCDRIVE had fixed the problem, the updated plugin should be already there for automatic update by now in 2019.
3. Maybe heed the moto "Sell it buy a VW" and get rid of the UC400ETH and buy Pokey 57CNC instead.

he is talking about SOFT LIMITS, not LIMIT SWITCHES

do you have torqe on the Motor if you Switch on power?
how are the dip Switches set?

can you see the Motor does one step,if you take the PUL- wire and put it on GND terminal of the Bob?
