Mach4 General Discussion / Re: tool changer tips and tricks

 Mark , I know that the Fadal carousel has a hall sensor that sends a pulse to the PLC . To either increment the tool count up , or down , depending on rotation of carousel . Fadal has a Geneva wheel drive mechanism that rotates the carousel 1 tool position per 1 revolution of the Geneva mechanism. I would think homing the carousel would not be needed , you would just have to save the current tool to memory somehow upon power down?

Hey Mark , I have no insight for you on lua script . But I am interested in your toolchanger outcome. I am retrofitting a Fadal with 21 position tool changer , and the
knowledge or time just isnt available yet , as far as I can find out . Several have done it but with different style TCs and using a plc. Good Luck with your project , I may need some help with mine when your done!!

dspMC/IP Motion Controller / PID Settings for Brushed DC Motors

« on: September 24, 2017, 04:41:53 PM »

     I need some guidance with tuneing the PIDS for my Retrofit Project , I can get the tuning good at high speed or low speed but no happy medium .
On X axis my P is 8500 , I is 500 , D is 6500 . Feed For is 2000 . Moves great at 400IPM , but at 20IPM it rings and the drive and motor sing? Ive got 5 Hours in it and only Y axis is good?
This a very large heavy machine with Glentek 4050 Motors and drives . Any advice ?

   Ive found a DL05 PLC in a Small Hydraulic Unit I bought awhile back . Do think it would work for my Tool Changer?

  My machine has a  25HP Spin motor with 1000 Line Encoder for Feedback to VFD , the VFD has encoder outputs which I hooked to the dspMC to provide Spin Speed Feedback to Mach.
I thought the Vital System dspMC would close the spindle speed loop . Isnt there a way to Scale the Analog output of the dspmc to synch up the speed of the spindle.

Mach4 General Discussion / Re: Quality Limit Switches for Fadal VMC ? What are you using ?

« on: September 18, 2017, 08:04:45 AM »

   Thanks Steve , Just ordered 10 of the Switches , I needed 2 more for home switches on my A&B . This machine has several Hall Style Prox on it with 5V .
So your saying I need to put a 24v Powersupply on for the home and limit switches ? Does the higher voltage just help with the switch lag?
Thanks Again for the Knowledge Everyone!
