hello,
i just updated to 2106 which worked fine. there is just one issue with my z probe macro which worked fine in 2049. between the g31 moves it does not move the z axis up 2mm. here is the macro:

//Simple Probe for Zero
//This routine probes in negative Z at the current XY location
//Z offsets for G54 to G59 are then re-written to the new Z0

double ZRetractHeight = 2; //Height above Z0 to which probe will retract
double CoarseRate = 200; //Feedrate for initial probing
double FineRate = 100; //Feedrate for fine probing
double Zmin = -20; //maximum probing distance

double PlateThickness = 32.44; //thickness of the probing plate
double MaterialOffset = 0; //compensation for part thickness

double CombinedOffset = PlateThickness - MaterialOffset; //really for use later when PlateThickness and MaterialOffset are DROs



exec.Code("G91 G31 Z" + Zmin + "F" + CoarseRate); // Probe Z quickly to get rough height
while(exec.IsMoving()){}
exec.Wait(200);

exec.Code ("G00 Z" + 2 ); // Retract 2mm above the plate /////////////////////////////////////////////////////////////////////////here it is not working any more
while(exec.IsMoving()){}
exec.Wait(100);

exec.Code("G31 Z" + Zmin + "F" + FineRate); // Probe Z slowly for better resolution
while(exec.IsMoving()){}
exec.Wait(200);

exec.mainform.sumoffsetcontrol1.G54.newCzinput(CombinedOffset); // Set G54 to new Zzero
exec.mainform.sumoffsetcontrol1.G55.newCzinput(CombinedOffset); // Set G55 to new Zzero
exec.mainform.sumoffsetcontrol1.G56.newCzinput(CombinedOffset); // Set G56 to new Zzero
exec.mainform.sumoffsetcontrol1.G57.newCzinput(CombinedOffset); // Set G57 to new Zzero
exec.mainform.sumoffsetcontrol1.G58.newCzinput(CombinedOffset); // Set G58 to new Zzero
exec.mainform.sumoffsetcontrol1.G59.newCzinput(CombinedOffset); // Set G59 to new Zzero

exec.Code ("G00 Z" + ZRetractHeight); //Retract Z axis
while(exec.IsMoving()){}
exec.Wait(200);
exec.Code ("G90");

thanks for help,

The test version 1.2106 had many issues due to lots of updates in a single update. Please try it with 1.2109 which is the latest test release.

version 2109 works better, it executes one time the g31, retracts 2mm, does not execute the second g31 and then retracts the last z move.
i change the macro to just probe one time so it works for me now.

great that you added the tangential control. maybe i have to get ucccnc for my second machine then

i really like uccnc, it feals much more solid then mach3. much less prayer when working with the machine

Hi Michael,

I modified your macro to show the Z machine coords at the beginning and after each movement. (Also commented out the G55..G59 resets, only to save my offsets.)

Code: Select all

//Simple Probe for Zero
//This routine probes in negative Z at the current XY location
//Z offsets for G54 to G59 are then re-written to the new Z0

double ZRetractHeight = 2; //Height above Z0 to which probe will retract
double CoarseRate = 200; //Feedrate for initial probing
double FineRate = 100; //Feedrate for fine probing
double Zmin = -20; //maximum probing distance

double PlateThickness = 32.44; //thickness of the probing plate
double MaterialOffset = 0; //compensation for part thickness

double CombinedOffset = PlateThickness - MaterialOffset; //really for use later when PlateThickness and MaterialOffset are DROs


Console.WriteLine("");
Console.WriteLine("0: " + exec.GetZmachpos().ToString("F6"));

exec.Code("G91 G31 Z" + Zmin + "F" + CoarseRate); // Probe Z quickly to get rough height
while(exec.IsMoving()){}
exec.Wait(200);

Console.WriteLine("1: " + exec.GetZmachpos().ToString());

exec.Code ("G00 Z" + 2 ); // Retract 2mm above the plate /////////////////////////////////////////////////////////////////////////here it is not working any more :o :o :o
while(exec.IsMoving()){}
exec.Wait(100);

Console.WriteLine("2: " + exec.GetZmachpos().ToString());

exec.Code("G31 Z" + Zmin + "F" + FineRate); // Probe Z slowly for better resolution
while(exec.IsMoving()){}
exec.Wait(200);

Console.WriteLine("3: " + exec.GetZmachpos().ToString());

exec.mainform.sumoffsetcontrol1.G54.newCzinput(CombinedOffset); // Set G54 to new Zzero
/*
exec.mainform.sumoffsetcontrol1.G55.newCzinput(CombinedOffset); // Set G55 to new Zzero
exec.mainform.sumoffsetcontrol1.G56.newCzinput(CombinedOffset); // Set G56 to new Zzero
exec.mainform.sumoffsetcontrol1.G57.newCzinput(CombinedOffset); // Set G57 to new Zzero
exec.mainform.sumoffsetcontrol1.G58.newCzinput(CombinedOffset); // Set G58 to new Zzero
exec.mainform.sumoffsetcontrol1.G59.newCzinput(CombinedOffset); // Set G59 to new Zzero
*/

exec.Code ("G00 Z" + ZRetractHeight); //Retract Z axis
while(exec.IsMoving()){}
exec.Wait(200);
exec.Code ("G90");

Console.WriteLine("4: " + exec.GetZmachpos().ToString());


I got the following results in the console window after running the macro 4 times:


As you can see, all the movements were perfect. Does it work as you described when you start UCCNC or do you run any g-code before the probe? Maybe, the g-code changes something?

i did run it directly after uccnc start, no gcode before.

Could you enable and show the console plugin, run my modified macro and show what is in your console window?

FYI, I tested with version 1.2109.

oh, now it seems to work. here is the console output. dont worry about the exact numbers, i did it kinda freehand. but it probed two times with z moves correct

UCCNC - Debug console
The Console can be used for macros and plugins debugging.
It shows strings written using the Console.Write and Console.Writeline commands.

i retried the original macro and now it works fine. i dont know what happened. i will report if there are again problems.
thanks for your help,

Fine!
