Why is it that when you're in front of something for too long you stop "seeing". Making too many changes all at once- slides, drivers, bob, etc.
Yup, diip switches go the other way!

All is good and it's with great humility I say thank you.

Now, how to straighten the 9 foot bow in the bed...

Thanks guys!

Russ- yah, I thought about the setting thing and logically you are right. But I swear I checked and re-checked.....that being said, I'm goinna try the other direction and see.....and call the supplier just in case.

We ran the machine last night and it is accurate but slower than what I've built before.

No gearing or anything. Direct drive to the racks.

It does move accurate but can't do fast. Lose counts that way.
Current velocity is 160 with accel 4.

Not sure if I have an issue or not but thought to get anyone's input.

I've re-worked an older General Gorilla router machine(and yes there's no support) with an XHC Usb 4 axis card and larger drivers for the NEMA 34s.
We don't know the exact pitch on the rack and pinions but when measured on calipers the pinions are 16 tooth and 0.741 in diameter. Metric = 18.83. The rack measures approx 8 teeth per inch.

I'm now set to the lowest micro-stepping (400) on the driver and when using the Mach3 calibration feature I get around 19K steps per (inch).
It seems accurate when running but those numbers look higher than normal to me. 

Does anyone see an issue running it this way?

Is there any Gorilla owners that have done a similar upgrade?

Is there anyone with a similar high count machine or is it just me : ) ?

Thanks!

Ian

Hi all.

Just joined the group and got started with Mach3. We're building a Plasma machine and can't wait to use it!

I did have an issue with installing but think it was just due to the Avast antivirus.
