General Mach Discussion / Help on new Build, Y not homing no matter what I try

« on: November 28, 2019, 08:57:11 AM »

I have a new CNC (Mach3) build I just completed and itching to try it out. Everything works EXCEPT Y homing. I currently have it setup based on some references here with the A axis slaved to the Y, that works I can job back and forth fine. I have 2 end stops on the right Y side, one for Y HOME and one for Y++. I have one endstop on the left Y set to A HOME. I can see the switches change states if I manually trigger them and Idle is grey on the screen so they are not inverted. In Homing I have X Neg, Y Neg and A Neg all setup. I changed the script for the Ref All Home to what was found here for homing dual end stops.

Now, here is where I don't know what is failing or not happening. If I press the button X homes just fine, then nothing. I get the script done message (it just sends a few DoButton()) and that is it. The odd thing is if I try and jog at this point, it says you cannot jog during homing so Mach thinks it is still homing but the Y axes Never moves. I do have A set as the Slave axis to Y and have Unchecked the Home Slave with Y as noted here somewhere. I even edited the script to just send the Ref Y and also tried just pressing the Ref Y button and it does nothing but make Mach thing it is homing and I have to reset after each attempt to get where I can jog.

I have tried looking everywhere for anything useful as far as debug goes but mach doesn't really output much to give me any hints. I am using the DDUM4 board but do not know if mach sends a special homing command to the board or if it just moves the motors and waits for a switch hit, either way the Y axis Never moves while trying to home. I figured if the inputs were wonky it would at least think it was homed and do the backoff but that never happens either. Any thoughts?

Finished Plugins for Download / Re: A new Huanyang VFD plugin

Mystery solved. If you have any spindle spinup delays set in general then that seems to set a Dwell that will never end and keeps any following M3/4/5 commands from completing.

 

I am just getting around to trying this VFD modbus plugin with my HY spindle. The spindletalker2 v.5 works fine and I can start / stop and reverse the directions all I want. I cannot get MAch3 to reliably work with it. I setup the plugin and it detects my VFD settings and I can set an RPM and start the spindle and see it ramp up and run. I can then stop the spindle with F5, but after that I cannot start it again until I reset. I also cannot get it to reverse direction at all. I did notice the DWELL indication comes on then stays on, is that related to it not responding after the first time? using driver v1.7.1 and Mach3 (latest version).

General Mach Discussion / Re: Motors / DRO not moving to issued pos

Will do. This is what I needed. I figured it had to be related to path planning and I am coming from the 3d printer side and things seem to work differently.

If you add a G61 at the start of your code it will work OK.

Perhaps read up on Constant Velocity, Axis Velocity and Axis Acceleration for just how it affects the toolpath.

General Mach Discussion / Motors / DRO not moving to issued pos

« on: August 07, 2019, 10:05:36 PM »

I was starting to test my Mach3 / Y axis setup and have the motor steps set correctly based on the setup I am using. I can issue a G0Y12 and it moves to the 12” mark just fine. The issue I am having or not understanding something is if I write a quick test script to move from Y0 to Y12 and back then loop (M47). It moves from 0 to about 10.5” and the DRO on the screen matches then moves back to 0 and repeats. For some reason it will not move to 12 where I have the Gcode moving to. If I manually issue the same commands via the Input box, it works. If I add a G4 P0.5 after the move to Y12 before the G0 then it works also. Almost like the planner isn’t giving the moves enough time before moving back (based on accel and max speeds). What am I overlooking?

G0Y12
G0Y0
M47

Moves from 0 to 10.5~ and back and repeats, showing the same positions on the Mach3 screen.

G0Y12
G4 P0.5
G0
M47 works

G0Y0 then enter on the Input box followed by G0Y12 moves to 12 correctly.

General Mach Discussion / Re: Error after Closing Motor Tuning Mach3

Works fine on the computer I was
Going to use it on (win10). The initial laptop I was using for testing (win7) has the crash.

General Mach Discussion / Error after Closing Motor Tuning Mach3

« on: August 06, 2019, 03:50:04 PM »

I am getting Mach3 setup on a new system (I can't use Mach4 because as far as I know, the DDUM4 board is not supported). I was trying to configure the steps/in/mm and I can enter the steps in and click Save but when I click Ok (or just try and close that dialog box), I get an error from mach and the options to try and continue or stop and if I click Y to continue it keeps showing the same error and No closes the program. So I am stuck not being able to set the steps for my steppers. I even looked thinking I can maybe modify the config file directly but it seems to be a binary file. Anyone else see this or know a way around it? Mach3 .43 (only download on the Download section, so I assume it is the latest build). Windows 7.
