General Mach Discussion / Re: Motor Controller front panel control suggestions?

So is there any other button that is Mach3 related that really should be on the front panel??

I have a Shibura Roibot that has been modified. it has stepper motors. and has a 20"x20" table size. I am crafting a custom Motor controller based on a Toshiba TB6560 3-axis board.

 The hardware i understand. what i could use some help with is the basic setup. I understand much of the software but some of the basics of configuring the size of the mill in the software so it knows where its limits are. steps per inch. all the basics initial software setup and tuning stuff.

 I will send a pm

I will have to double check but i believe it is around 400hz. the higher in freq you go, the more motor heating you experiance due to the inductance of the motors coils. so there is a limit to how high of freq you can run. higher the freq, more power but higher temps also. so you have to play with it a bit. i think when i started i was around 100hz but i cant remember what the final number was i settled on.

I sent an email to the SuperPID people asking about a PWM version. will see what they say.

Oh look at that! I couldn't find anything like that to buy so i had to build one LOL! that is a super nice unit! I like the RPM display and motor Load bar graph! those are really nice touches. wow! thanks for posting that link!


I wanted to be able to choose the speed from within Mach3. and mach3 has the uber cool PID function and PWM signal generation built right in it! from Mach3 i can set the spindle to an exact RPM, ie: 6550rpm and it will run at that rpm or even change speeds while machining. maybe for different operations etc. and mach3 does all the work! and with PWM you have more power at lower RPM.s vs a Triac based speed control type system.

BUT that superpid is an awesome stand alone unit with some really really nice features! I thought about building a completed version of my controller to sell but there didn't seem to be much interest.

General Mach Discussion / Minnesota Mach3 Users?

I am curious how many Minnesota Mach3 users there are? I am looking for some help to tune my mill and would like to get in touch with some local users that would be willing to help me get the basics set up.

 It might also be fun to form a MN mach users group and get together once a month or something. any takers?

This controller works VERY well! I need to next build a Pulse feedback system to take advantage of the speed feedback function within Mach3

I think the schematic was way too big in size causing some problems...sorry for the multiple postings
