Anybody...

Or the anti backlash nut is not holding the nut properly or meshing with it properly.

Checking for a small amount of missed steps is best done by the verify function as dharmic mentioned above, your switches (optical or mechanical) should have a good repeatability also.

If missed...

Just a quick note here on what I am trying to achieve, I am not trying to better closed loop systems or reinvent the wheel. Its just a $100 to $150 budget with the screen to get all this passive...

Thanks for the info and links, very interesting. The encoders I will most probably be using at a later stage (funds...) I'm just a hobbyest, and don't get income from my CNC, its just for pleasure. ...

You are right, Its kind of Passive Safety not Active. The way I am programming the Arduino is to count the number of pulses on every pass of the encoder (notched or un- notched part); the pulses have...

Thanks but I only use Mach3. Mach3 does monitor the spindle rpm but to my knowledge you can't configure Mach3 to engage EN safety and turn off spindle if the rpm's are very low or the current is very...

I am a hobbiest and this is my first post, thought to share and take opinions of what I am doing. Its more of a self challenge project to learn more about electronics and Arduinos teensy etc…

I...

It was not calculated, more of a feeling, and recall reading a close figure around the forums, cannot confirm though which forum. I have been doing some milling around the 1 to 2 cc/min and felt the...

Talking about the limits of the sherline, I do agree that the Z column is the weakest link in the mill, but going up to 9 cc/min is quite high in my opinion. As I understand, the power of the spindle...

Thanks a lot acannell for the valuable info!

you have really encouraged me to go deeper (DOC) in my cuts, 1 mm (0.04" is the deepest I have attempted)

With the machining parameters in your last...

I had similar issues on my sherline, but I would usually restart the computer when it happens, and the issue would be solved.

This is my first post here, and was thrilled to hear about the sherline, as I also have the 5410 CNC version (metric).

I am usually at 200 mm/min (~8ipm) but what I did, instead of getting the 10k...
