Re: Spindle self rotates on start up!

Hi All. Solution update, after more testing the earlier solution still was not complete. The version below has been tested in every factorial combination I can think of and and multiple times for each combination. 1 - Link the work lamp relay to a solenoid output eg relay 6 2 - Install a 5 second de...

Re: Spindle self rotates on start up!

I have thought a lot about the comments above and for the most part you guys are very correct. There is however one comment I'd make that I think is fair and square. Acorn should not be generating thousands pulses of its own accord during start up. This point is very very strong. I am an engineering...

Re: Spindle self rotates on start up!

Minor Update

Did some testing and the spindle will still move with the probe plugged in. (No commands given!)

Cheers...mk

Re: Spindle self rotates on start up!

Update, There seems to be no other other output that resembles the no-fault-out signal enough to be used to safety enable the spindle motor. My choices 1 - Continue to allow my spindle to randomly move (Yikes) 2 - Remove all fault conditioning from my spindle motor (Yikes) 3 - Risk damaging all my e...

Re: Spindle self rotates on start up!

Update, The no-fault-out relay is busy powering the CNC4PC clearpath breakout board (and not the spindle enable). The surge of unexplained PWM signal remains a mystery. I'd like to request a really simple enhancement When you drag outputs from the list in the wizard they disappear meaning you can't ...

Spindle self rotates on start up!

Hi All, When booting Acorn my spindle rotates without being commanded, this seems pretty dangerous and the motion occurs before the 9033 reset is cleared. To replicate 1 - PWM spindle mode 2 - Powered acorn off then back on while in centroid 3 - Restart centroid Outcome 1 - Software starts booting 2...

Re: Clearpath MCVC Spindle Motor Control - Solved (Mike R is a legend)

Hi Mike R, First up i think this is the best start to a post I have ever seen "I was not satisfied with yesterday's test" Next "but it would probably require a lot of manual editing if you use a CAM program to generate G-code" >> yikes no thanks, I am on team "keep it simple...

Re: Clearpath MCVC Spindle Motor Control - Solved (Mike R is a legend)

Hi Mike R,

Just a quick update, I have barely been home for a few days so apologies for the delayed response. I'll digest and get back to you!

Many thanks...gMike
