I am a big fan of the Vital System stuff although I have just purchased a Pokeys57CNC for a new project.

RMH,
Glad to see you are still with us.
I would just make sure that the controller you get does the functions that you need. If you need lathe threading for instance right now, make sure that it is supported right now, not at some future date.

Have done bearings before it is sometimes amazing how much a bearing will expand (without damage) with some heat being applied. And just how strong a shrink fit can be.
IIRC "BT" holders are metric and CAT are imperial. The drawbar in my BTC-1 is two piece. If drawbar is being activated by an impact gun I am not sure you could get away with a two piece unit.

My son just made a drawbar for his M-head mill and he made it out of one piece. His is shorter than what you need. It fit on the Monarch CK-12 no problem.

Dave, you said you were not going to grease the bearings this time you were going to oil them IIRC. How are you going to supply them with oil on an ongoing basis??

Feedback ratio is for confirmation. Maybe you have an encoder for this with 1200 pulses per rev. Well, Mach can't determine the feedback ratio because it doesn't know what the feedback is reading, drive or driven or how many times it reads per rev., etc. ...... so you have to tell it.

There is no place to enter a ratio. Only the max RPM of motor and max RPM of spindle for different ranges in the spindle configuration dialog. Mach4 is smart enough to determine ration based on those 2 inputs.

So, if your motor has a max RPM of 4500 and Range 0 has a max RPM of 4500, then its 1:1.
If the motor has a max RPM of 4500 And Range 1 has a max RPM of 9000, then Range 1 is 2:1, etc.

It might pay you to temporarily forget some of what you know about 3 and study up on how 4 works. I only say this because they are different. 4 is better IMO but lots of things are different but usually in a better kind of way. If your moving to 4 and assuming you know how to do things because you know how to do them in 3 you will likely pull some hairs out. Maybe all of them.

Thanks Craig!

First, I went in and configured the Limit Override in the Pins Config to be the F12 key, but it still wouldn't allow the machine to reset.  Not sure why that's even in there, if Mach ignores inputs when it is disabled, how would that even work?

Then I discovered the Auto Limit Override in the Configuration screen, checked it, and everything was OK.

A little hairpulling for a couple of hours, and I don't have any to spare.

What specifically do you have for software Cam,
and Mach version / setup. What size of machines
do you have?
What basically do you want to accomplish?

Hello again,

after watching a youtube video, in which a user of pokyes has shown lag when using IOs to switch OEMTrig in the mapping, I switched over to calling OEMButton 301 and setting OEMLeds in the mappings, only to be sure to have no lag when pressing a button. Working so far.

But again I have got the problem, that sometimes no macro call is working in mach3. Beeing it over my matrix-keyboard or over the screenset itself. I figured out, that every time I use the MPG to move my axis, all macro calls are blocked. When disabling the MPG over the screenset, I can call macros again. Over the matrix-keyboard and the screenset.

Do somebody else have this problem or is it only me? Ist this a mach3 problem or could it be, that it's related to the used Pokeys57CNC?

I am thankful for each reply, specially if you have experience about that.

I thought about shorter usb cable, existing one is like 2m long. My boss ordered new one. Getting it soon.

I noticed this card have PE connection, but there are no wire connected to the ground. Is it ok to ground it?

Auto tool zero mostly works fine with original version of driver which came on CD, but all errors ever happened appeared time to time. MOstly it is working fine for 1-2 months and then for 1-2 weeks it sucks as fck. It happened few times that spindle is losing its correct position even while program is running.

I thought now also I should check which version of Mach3 is installed or reinstall software. Never know ...

PS! I know about that ********* related with china products. I got my personal experiences with these and all things I ever bought for myself stopped working in 1-2 months. I dont have any mood to order anything from china or hong-kong, waste of time and money.

Hi,
broadly speaking that's what the feedback ratio does. I think the idea is that spindle will be close loop stabilized by the feedback and if the feedback ratio is chosen correctly
the actual spindle rpm can be chosen correctly as well.
I'm not familiar with a gear ratio in Mach4.
