Holey Triangular Calibration

the measures are from center to center? I can’t find details of from where to where should the measurements be taken.

center to center, left to left, right to right, they should all be the same, do whichever works easiest for you.

One of the videos on that wiki page shows it being done.

take your tape measure (any), and start measuring from the 10mm mark. When you get your final measurement, subtract 10mm and that is how you can measure accurately. No need to buy new tape measure or reinvent the wheel.

Hello All - newbie question. I’ve just purchased an original maslow. I am trying to upgrade the firmware for the holey calibration as described here - How To: Holey Triangular Calibration (GroundControl and Firmware).

I have downloaded the holey firmware. When I attempt to upload the compiled cnc_ctrl_v1.ino file to the arduino, I get this error - redeclaration of ‘float Tension2’.

Can someone point me in the right direction?

Thanks in advance,

Scott

The easiest way to do the firmware update for holey calibration is to download and run webcontrol. In webcontrol is a button to upgrade to Holey firmware and it will do the rest.

Orbo - thanks for the insight. I’ve got webcontrol running. I’ve tried to do the firmware update a couple of times, but it does not seem to update. The terminal seems to close the connection and then nothing. I’ve given it a 30 min. That seems to be more than enough time to download and install. Here is a screen shot of my terminal window.

Any thoughts on what may be happening?


Thanks

that window appears to be normal communication, not reprogramming. It might be faster to open the arduinoIDE and manually flash it with 51.28. I can’t do much for you and the mac, since I don’t have one and it has been since Tiger or leopard that I last used one.
