4 axis lathe with Acorn board - third axis not working
Building a 4 axis machine to be attached to a woodturning lathe. Z, X, Y for linear movement, A for driving the spindle. VFD driven router to be controlled by Z, X and Y axis.
Have installed CNC12 Lathe software, no problems setting it up on the bench function test. CNC12 Wizard set up all four axis.
All 4 axis show up on the display, but the virtual pendant does not show jogging for the Y axis.
I have the three linear axis wired for bench testing the motors. Waiting for delivery of the motor/driver to power the spindle (A) axis.
All but the Y axis work as expected. Screen display on X, Z and A follow all g-code instructions, but any Y entry instruction results in an "invalid character" error message.
What have I missed?
X, Z, Y Motors: Leadshine ES-M23480-S (Automation Technologies: KL-34-8N-1000)
Drivers: Leadshine CS-D1008 driver (Automation Technologies: KL-8082H)

Re: 4 axis lathe with Acorn board - third axis not working
Can you post a screenshot of your Wizard "Axis Setup" Tab?
And a current report for those guys that actually know stuff?

Will have it done in the morning - taking a bit of time to watch some winter olympics on TV tonight

Re: 4 axis lathe with Acorn board - third axis not working
Screen shot of Axis set up. My present machine is a table 3 axis, with a rotating axis on the X axis plane - used to using A for rotating axis, reason for original post using A for rotating axis.
New build uses the rotating axis on the Z axis so set up is C for rotating axis...
All settings for motors are Wizard entries.
Still working on my problem. Y axis displayed but not responding to commands.
Plus - is there any way of adding the Y axis to the jogging screen in CNC12 Lathe software?

Re: 4 axis lathe with Acorn board - third axis not working
Y is not a valid axis in the lathe software.(I don't know why at the moment -I'm looking into it)
You can use A & B instead. C is a function specific axis, can only be enabled with a G51, and you would not want to label a simple linear axis as C.
4th axis requires Pro software to command - I'll look into adding the jog key(s) back into VCP for 3rd and 4th axis.

Re: 4 axis lathe with Acorn board - third axis not working
I'm running CNC12 Lathe Pro, so should have all the options available.
Tried A and B names for "Y" axis. Both work when using MDI command, but still get "501 invalid character" message when running a test .txt file.
Had only used G0 for movement so far - now added G1 commands and find that everything seems to stall and the feedrate display does not read mm/m, but mm/r.
Same is happening when using the MDI. Changing speed (F) only changes the number in the feedrate display, no effect running the axis. Screen shot below.

Re: 4 axis lathe with Acorn board - third axis not working
Please ALWAYS post a report when requesting support. If your question also involves a gcode file, please ALWAYS post that as well. Without them, we don't have enough information to help you.
Nothing is stalling, your are commanding motion in feed per rev without the spindle running. Hence no revs = no motion.
G98 - Feed per minute
G98 sets the cutting feedrate mode in units/minute. There are no associated parameters.
G99 - Feed per revolution
G99 sets the cutting feedrate mode in units/rev. There are no associated parameters.
Change your command to G1 G98 A1 F10
How does it work now?

Re: 4 axis lathe with Acorn board - third axis not working
Now all working, hope to see a change in the VCP to add the extra axis.
Used to writing gcode for my four axis table top CNC, with A as the rotating axis.
G98 - G99 not used there - now burned into my memory!
Thanks a lot, I appreciate the help!

Re: 4 axis lathe with Acorn board - third axis not working
I would pay money to see a video of that puppy running a job...well almost. I'm sure there are many others here that would like to see what you're doing with it. Do you have videos up already or do we have to MAKE you do one.

Re: 4 axis lathe with Acorn board - third axis not working
Don't have a video of the 3 axis machine with 4th rotating axis - yet -
Will be running it some time next week or so, will record it making one of my production parts.
For this build, I'm only at the electronics bench testing stage. Video of motors turning not too exciting. Still have to get misc parts and cabinet to put it all together. It's the part of the build that I can do without toooo much frustration.
Mechanics will not be finished for some weeks.
Would like to take credit for that, but have a friend who makes complex mechanisms for a living and is generously making my machine in his spare time. It's a good thing as there is nothing commercially available that will fill my requirements.
