Re: Acorn to G203v Pullup Resistor

FWIW (Assuming no internal pull ups)

5VDC = 470 ohm
12VDC = 1.1K ohm
24VDC = 2.2K ohm

All = ~10ma

5VDC = ~.05W
12VDC = ~.13W
24VDC = ~.26W

Re: Bench testing. Spindle won't turn off

Please run the wizard and select benchtest radio button on tab #1 and then write settings. You have a single output defined as SpinRev, this is not a standard benchtest setup: OUTPUT1 IS OUT1 ;&*; OUTPUT2 IS OUT2 ;&*; SpinREV IS OUT3 ;&*; OUTPUT4 IS OUT4 ;&*; OUTPUT5 IS OUT5 ;&*; OUTPUT6 IS OUT6 ;&*...

Re: Intercon (offline) G84 tapping?

You can't make the spindle run in offline. I thought you meant you were generating your g code in offline but running on control.

Re: Intercon (offline) G84 tapping?

Is the spindle running? (it looks like it's running CCW. Depending on your M29, it may be waiting for the spindle to run CW. For rigid tapping, Z axis movement is slaved to spindle encoder.. From the manual: Parameter 36 - Rigid Tapping Enable/Disable (check in both offline and control) This paramet...

Re: Silly Spindle Speed Stuff

It looks like you need to wire your system as shown in fig 4.1 on page 14:

You may need to tie the VFD COM to the Acorn COM.

Wire SpinFwd to X1, SpinRev to X2 See page 38 for parameter settings

Re: Silly Spindle Speed Stuff

Please always post a report.zip file when requesting support. With your configuration to reference, we can't provide any useful info in troubleshooting your issue. I'm going to guess that your spindle range ratios are incorrect but without the config info we are completely in the dark. To create a r...

Re: Homing Directions

Motion is always defined as the tool relative to the part. It doesn't matter if the mill is a moving table design or moving tool. As for homing a knee or bed type mill, Z is homed first in the positive direction. I greatly recommend homing the Y next in the positive direction. If you a vise or work ...

Re: OAK Encoders reading backwards

If you can currently motors move under control but commanded motion is in the opposite direction to what you expect, then use direction reversal as Keith directs. If you motors just jump and you get a position error, then you will need to swap the polarity of the analog speed reference at your drive...

Re: Homing sequence

No custom PLC needed, M105 and M106 look for the state of an input number, no PLC logic needed. You could set them to unused in the Wizard if you like. M92 /Z L1 ;Move to Z+ home switch, back off until it clears. M105 /Z P-4 F3 ;Move Z minus at 3ipm until input 4 closes M26 /Z ;Set Z home here M91 /...

Re: CNC Wizard Disabled?

It doesn't look like you have anything configured yet so I would suggest going into to add/remove programs and uninstalling CNC12. Delete your c:\cncm directory and try doing a clean install. You probably deleted a file that the Wizard requires to run. The next version (4.10) this week is more verbo...
