Hey everyone, Ordered the 80mm mount as I have a 80mm spindle I’d like to try. Given the weight, considering upgrading the Z-axis stepper and was wondering if there is any guidance on what size stepper I should look at. Given the buildbotics should be able to handle most of the comparable Nema 23…

[20210811_204346] I have an upgraded x50 woodworker, 80mm 2.2kw spindle, and very happy with the combination. I did not change any of the stepper motors - everything seems to work great.

I wouldn’t be too upset about the threads. A trip to the hardware store and you can get a new set screw and tap of a slightly larger size. Larger size means larger allen wrench which is less likely to strip.

Andy, Before you give up hope, get new set screws and try. Given what I am seeing in your pic, the threads in the set screw seem fine so you may be able to just replace them. Also, as someone else suggested, if the original size set screws don’t work, get a tap and one size larger and just retap t…

Hi, I’m going for the re-tap. I’ve ordered some hex screws. Fingers-crossed. Alternative is to ask 1F if they can supply me a replacement part. Just didn’t feel right to drill out glued in screws to perform an OEM purchased upgrade. I assume 1F has had to glue the screw in because it’s role is t…

Hey Andy, I agree with the others that from a technical point of view, your Z Slider isn’t lost. But if I were you I would first send an E-mail to support@onefinitycnc.com and write them something like: Why do your instructions in the video “ Support: Swapping the Spindle Mount on the Onefinity CN…

[image] 349iq2345: But a method to lock a screw that I technically prefer much is a Lock Screw , i.e. a second screw that is screwed against the first. Now that’s a smart idea. I think I’ve trashed the first half of the threads going in. So I’ll ponder whether to re-tap all through or just …

Hey all, does one of you remember that before this video was there, there was another video covering the same topic, but it was of less quality. It seemed to be made with a smartphone held by hand. You could hear the noise of assembling and testing cncs in the background (stepper noises), and the p…

[image] 349iq2345: But a method to lock a screw that I technically prefer much is a Lock Screw , i.e. a second screw that is screwed against the first. Hi - this isn’t possible (as I found out) as the two plates use the same hole for 2 of the 8 threaded holes therefore there is not sufficient…

The 80mm mount moves the spindle out a bit so that it can be raised up higher than the stepper. The clearance on the front is quite small - about .1", but I can’t measure it precisely. [20210908_163309]

Michael, how much is the distance between your 80 mm spindle and the stepper?

Air cooled spindle?
