General Mach Discussion / Re: Calibration Issues - odd results

You really only have to do it once in an accurate measure (dial indicator) make a move say 1" and then apply what teh dial indicator says it moved let mach do the math and reset the values. Retest to confirm it is correct.

IF the 1"move is correct to .001 then rest of it is correct as well as far as mach is concerned.

Each axis is done the same way.

NOW if your screw mapping is way out then that is another story

OK I think I see the problem. Go an turn OFF all the modbus stuff you turned on.

Then load the driver and look to see what port# it is using.

Then go to GenConfig page look in the lower LH corner and set the COM port to the one you are using. Check 8 bit.

That will set up mach to use the com port .

Then retry your code to see what happens.

Are you using the USB driver for the card ? Have you tried the software for the card to make messages to SEE if it is actually working correctly?

Maybe set up hyperterm and send it some data??

There is probably a setting for the LCD that needs to be set to stabilize the screen. I'll take a look

You are not really using ModBUS the SendSerial VB command is a seperate thing it sends data straight to the serial port. AND it is not really RS232 protocal.

OK I have no idea if this will work but give it a try. WHat we are doing is sending 1 long string of everything. Everything is spaced out so when it line wrappes ALL the stuff lines up on each line(hopefully)  If you need to adjust it do it in the " " at the each of each line the spaces are empty holder places ADD or subbtract a space to adjust. Basically each line is 16 charectors lone then it wrapps the line.

The "?Y0,?X0" SHould be the starting point of the Matrix, Row 1 column one

We may need to send a blank page each time but try it first.

XV = "X: " & Format (Getdro(0) , "+000.0000;-000.0000") & "    "
YV = "Y: " & Format (Getdro(1) , "+000.0000;-000.0000") & "    "
ZV = "Z: " & Format (Getdro(2) , "+000.0000;-000.0000") & "    "
AV = "A: " & Format (Getdro(3) , "+000.0000;-000.0000") & "    "
MS = "?Y0,?X0"
SendSerial "" &MS &XV &YV &ZV &AV

OK normaly when you write to an LCD you write to a position on a matrix such as row0 column 1

For a 4x20 display you would have rows 0-3 (4) and columns 0-19 (20).

What you are doing is sending charector straight in and it just wraps the data around and around (linewrapping).

Look at the manual for the format for writing to the LCD display.

OOPS the sendstring is a modio control you are using sendserial.

You may want to try sending it ALL as a string instead of individual updates.

The USB pendants are normaly run with a PLUGIN.

Just a thought, (;-) TP
