Re: [Emc-users] Triggering an external relay from a BOB

Gene, Based on your response I believe you're referring to a PDM commanded spindle. I'm using PWMGEN pulses to drive my PM DC Motor. I think I have it now tweaked about as good as I can get it. It took a combination of modifying the following two HAL entry values: setp pwmgen.0.scale 7600 setp

I have encoder.0.position-scale set to 400 and I have all three phases A,B,Z enabled as inputs. Me thinks it might have to do with pwmgen.0.scale or the pwmgen.0.offset. Not entirely sure what those do yet. I believe scale assumes you know the max rpm the motor will run and sets the increments

The CUI ATM 103. The PPR is set at 100 both on the device and in HAL. I’m not using scale mode since I needed Quadrature in order to detect CCW for rigid tapping. On Tue, May 19, 2020 at 5:03 PM Gene Heskett wrote: > On Tuesday 19 May 2020 17:28:40 Dan Henderson wrote: > > > Thanks Gene. I

Update for everyone. I now have two working relays controlling the operation of the spindle motor via BOB and Parallel Port. I've also now successfully tested the G33.1 Rigid Tapping cycle with this setup. Relay #1 is used to power on/off the motor controller board (MC2100). (M5 or S0 triggers

Re: [Emc-users] Triggering an external relay from a BOB

I have two parallel port cards in the PC and so have the ability to leverage two BOB's for inputs/outputs. One BOB requires an external 5v supply the other is able to use a USB port from the PC for power. I'm going to bask in this small victory for awhile before attempting anything else :) On

Re: [Emc-users] Triggering an external relay from a BOB

I now have two working relays with LCNC control via the BOB! Both rated at 10a 28vdc MAX. As I mentioned in another thread, I do indeed want to be able to switch polarity of the spindle (low or zero rpm) to achieve CCW rotation. I also want to be able to turn the spindle on/off. Whether it's with

Re: [Emc-users] Triggering an external relay from a BOB

Hi, just to make sure, have you checked if your BOB has open collector outputs. If so you need to supply a pull-up resistor between output and +5V and the output needs to be defined inverted. Br, Andreas Dr. Andreas O. Lindner Lindner TAC Auhofstraße 11 B / 11 1130 Wien Austria Fax: +43 1

I was just testing any pin. I have two BOB’s connected to two parallel ports. All my steppers are working on BOB zero. No issues with any of that. BOB “1” has spindle-motion-reverse => paraport.1.pin-04-out. From this BOB I have both + and - 5v going to Inputs of external relay along with output

Re: [Emc-users] Triggering an external relay from a BOB

Sorry about the last reply written before seeing the posted manual. As Gene points out it is "14" or "4". But also, my guess is you need to supply 5 volts to the board via either a power supply or a USB cable. One why to debug this is to but a voltmeter on the relay coil and toggle pin 14.

Re: [Emc-users] Triggering an external relay from a BOB

My first guess is that the BoB can't source or sink enough current to energize the relay coil. But we have to know what exact relay, power supply, and BoB you have and exactly how they are all connected. Could you post a schematic? On Thu, May 14, 2020 at 5:33 PM Dan Henderson wrote: > >
