Acorn Wizard Data Excel Spreadsheet

Working with Keith and Marty we have modified the spreadsheet that was found on the MACH forum so it would give you the info you need to enter into the Wizard's Axis Configuration page. I hope you find this helpful when setting up your Acorn. Orin NOTE Some changes have been found that need to be ma...

Re: Touch Probe Signal Debounce

Hi Keith,

Thanks for the very quick answer regarding this. Can the ACORN perform the same probing as shown in this video?

I suspect that if the answer is "yes" then I'd have to get Centroid Ultimate CNC software.

Touch Probe Signal Debounce

Does the probe input on the Acorn have a contact debounce filter built in? I ask this because Renishaw mentions this in some of their literature and that accuracy is improved if you can filter out the bounce that is present in a kienmatic probe output. Here is a sketch that describes what I'm talkin...

Re: Stepper Motor resolution

Marty has given you all you need to know to hopefully get it working OK.

The only suggestion I would have is to take a 1 or 2 inch dial indicator and count the number of screw rotations it takes to move the table exactly 1 inch. I would do this for all 3 axis.

Re: Stepper Motor resolution

Not complaining Orin. Where would you enter the 20,000 in the Wizard? This is based on your example above. The 2:1 ratio would mean that the steps/revolution would have to be 2000 x 2 = 4000 or I guess the steps could stay at 2000 but the overall turns ratio would be multiplied by 2 which would be ...

Re: Stepper Motor resolution

While helpful, Centroid does it differently than Mach. So how is the Excel spreadsheet's calculations any different from ANY stepper controller? Just because the spreadsheet was found on the Mach forum doesn't mean that the calculations are any different from ANY controller that uses step/direction...

Re: OMRON E6B2-CWZ1X Encoder Unboxining and Overview

Thanks for the review and letting us know about the wiring issues. Have you had time to check to see if it actually works and ACORN reads it's output? Here is a breakout with the correct, usable securing screws: https://www.amazon.com/Adapter-signals-Terminal-Breakout-Plastic/dp/B01C2V2E8U/ref=sr_1_...

Re: Monitor mounts

I got one of these a couple of years ago and it works fine and is cheap.
