I'm trying to secure the J1 motor mount to the J1 motor housing, but the screw holes don't seem to be tapped? The holes in the attached picture look pretty smooth. I'm wondering if anyone has encountered this before? I'm considering tapping them myself.


That's great, I'm glad they are sending a new gearbox. I messaged them as well and they confirmed they are shipping it out to you. Stepperonline is really good about taking care of issues quickly. Thank you.
I haven't seen that issue come up before. I will contact Stepperonline to see if they have had any others. Let me know if you are able to tap this or if you have any issues.
