Probe bit dimensions

My machine arrived a week ago and I finally got everything working yesterday. Then I downloaded v.1.1.1 and now I can’t use the probe. I select X Y X Probe, a drop down list shows and first item is Check Probe. I check probe and next item is Bit Dimensions. I’ve tried everything, changing bits, moving bits up and down, etc, but nothing works. In the second column of the initial grid, the 0.05 in is in blue. I’ve looked at all the articles about probes on YouTube and the forum but none addresses my problem Please help.

Just a note. I spent a month researching cnc machines and one of the reasons I selected Onefinity was the owners who spoke about the excellent support all raved about calling you and getting their problems taken care right away. Imagine my surprise when I called and was told send an email unless you are looking for info on ordering.

Emailing support is the official, and best way, to get help.

Phone calls may sometimes be an option, but I do not believe they have the resources to have regular ongoing tech phone support.

Also, this forum is very active, knowledgeable, and helpful. I am sure others with experience will offer their support soon as well.

There is and never has been phone tech support :stuck_out_tongue:

It’s stated on our website, tech support is email only.

Some people confuse this forum for official tech support as well. Tech support is only officially done through

Hey Ron @Ron9577 , from what you’re saying, I think what you’re doing is placing the probe, connecting the magnet and then expecting the next order to come up and that’s not happening. You have to bring the probe up to contact the bit, then the next column comes up. There will be a drop down menu you can select your bit size from. Once you do, there’s a button marked “next”, hit it and you’re off to the races. The order of commands is changed a bit from the previous firmware iteration. Some like it, some don’t. I think it’s great. Anyway, try this and let us ( the onefinity users group ) know if that fixes your problem.


Thank you, Charles! I looked at that drop down a dozen times but didn’t realize it was a drop down. Yesterday was very discouraging but I used your info this morning and got started on a Halloween mask. Unfortunately the cedar fence board was harder than I thought and my clamps were not as grabby as I thought so the wood shifted and broke my bit. I’m learning but “slowly, slowly, slowly said the sloth”.

Yeah, one of the fun things about a CNC, now you can mess things up much faster than before😏 It does get better but even so, you’ll still mess up every now and then. It takes a long time to make enough “learning mistakes” to get good at it. The best ones are the most cautious. They double check everything, run checklists, do practice cuts in something throwaway, then do an "air cut " above the workpiece before they actually press go. They make it all look so easy.


@Ron9577 " slowly, slowly, slowly said the sloth". Yeah, my CNC guru says " you’re drinking from the firehose now":smirk:
