Can't get my turret to work on my lathe.
I have followed the Acorn axis driven turret procedure.
ACORN_4.14_Lathe_Axis_Driven_Turret.zip
Copied and pasted macro files.
I have set parameters 60, 160, 161 as per instructions
and I'm getting this message As per picture.


Please find attached files

Can you tell me what am I doing wrong?

Please explain the expected sequence of events.

The G-code on screen looks like the line is missing a ";" at the beginning of line, as this is a comment line the control needs to skip....

My turret is going to be driven with stepper motor.
In order to change tool the piston needs to be actuated that will push front plate assembly M10 (turret) and than stepper motor will index the turret to required position.
Once position of the turret have been reached piston will return. (springs on the assembly will take care of pulling the assembly back)
This can be achieved with M10 M11 Command
I have defined the parameter 161 to be consistent with 6 tools.
My stepper motor is also set that 1=1 tool position as per instructions.

As Centroid 188 says, if you look carefully you have typed a ":" instead of ";". So it doesn't recognise the character as a comment demarker and thinks this is a command with no parameters.

Thank you for help.

I have managed to get the turret moving and index properly.

Problem I have is when I power down machine and home it. Turret looses position displaying 0.
Also it doesn't seems to update tool nr just the offset nr
Obviously I'm missing something.


please find attached macro:

I don' know why, but when I run tool change from MDI turret always lands on right spot.
But when I run tool change from programme it seems to always counting incrementally.
