General Mach Discussion / Re: How can I get away from parallel cable
« on: December 01, 2020, 03:46:35 PM »
There are a number of Ethernet based sub controllers around, Smoothstepper is one and the UC300ETH is another. Both are good and offer a lot of scope for I/O expansion as well as breaking from from the ancient parallel port and its increasingly rare cable.

^ that's it exactly

I think this means that the acceleration/decelleration values are so low that it hits the limit switch and overruns due to the motor's programmed wind-down rate.
With this said Mach3 treats limit switches and home switches differently, hitting a limit should trigger a hard emergency stop but a home switch just acts as part of the homing process and won't interrupt anything.
Is it possible on your machine for the actuator to climb over the switch and release it before the motor has finished slowing down? I've never had this condition but it might cause wierd homing. Have a look at it and see if you can keep the home switch held as long as possible, raise the motor acceleration slightly or slow it down a little if this is a possibility.

just a thought, if you are using the same switches for homing and limits, make sure the ports and pins page is set up to reflect this.
Do you have individual pins assigned to each or are they all going to one pin?

Sounds to me like you just need to set the spindle lever up as your Z axis. pop a stepper and a belt drive on it and configure Mach3 to run with the MPG you have, and you should be good. With this said I think you'd be better off programming a drilling cycle for what you need doing, it will be more consistent, quicker and safer.

same here, I did it all with relay logic and being 3-phase it was fairly simple. it's got a spindle brake and a timer so that I can program m3, m4, m3, m4 all day and it doesn't crash but I have never, ever used it in 15 years.
Edit: my 300th post, I should make a cake to celebrate :D

This rather depends on what sort of limit switches you want but if you want professional grade equipment rather than no-name Chinesium then I'd go to RS. Although they are first and foremost a trade supplier they handle personal accounts too, and cash sales can be done via the website. Support is very good and as far as switches go, they have enough to sink the titanic. They do their own lines of cables, switches under the RS Pro line, and they are effective and well priced.

Farnell are also very good and sometimes cheaper - Best to check both.

Amazon sometimes do well but don't expect any kind of support, they're ok if you want basic stuff down to a price but I'd rather go somewhere that i can find the same thing a year later if I need to replace anything.

Words to the wise I'm sure but if you're using a changing parameter value for turning the diameter, make sure it is zeroed (or returned to a fixed, favourable value) every time the code runs. Otherwise it will persist and keep incrimenting itself over and over.

just go into the ports and pins menu and disable them ^
