That makes sense. I can imagine the amplitude of the vibration growing by the time it gets to the tool tip. My goal for this machine was to have something like an Avid 4x8. I thought with a beefier...

Really? They're old school, but seem plenty strong, given the machine is so flexy.

Hey cnc people! Im hoping to get some more help. I ended up going with the avid z assembly. It's pretty sweet and has totally solved the lost z steps issues. I'm really happy I went with it cause it...

The person managing that ebay seller profile is not helpful.

I called Avid CNC more more info about their assembly (it's missing from the product page). It's seems pretty awesome, it's got dual...

Would that be something like this? https://www.ebay.com/itm/320839352439

Interesting, thank you! I asked the seller of the low profile assembly for more info on the Kirk lead screw.

The first listing I posted is for a much cheaper chinese assembly. It says it uses a...

This one looks pretty slick!

here are a couple screen grabs for posterity

Well I went over the whole machine and it seems like everything was tight. However, as I tried to clean and re-lubricate the sliding parts I found the z movement to get much rougher. The ball screw...

Thank you, that sums up the issue very well. The z height in the dro does confirm it's loosing steps on the z up dirention. Hopefully it's just a loose set screw!

Hi all, so I'm up and cutting but I'm getting some odd results. I did my models and cam in Fusion360. The simulation seems straightforward and correct. But when I cut the 2D adaptive pocket the Z...

Hey, did you ever find these settings? I am trying to get a practical CNC going after a long rest and have no clue where to star with motor tuning.

Thanks very much for your replies and dropping the links! It's poor etiquette not to do the search myself, but it's easier to just have you to do it for me [emoji14] :joke:

Awesome! Thanks for your feedback.

I'll try to plug it into my desktop. AND TRY NOT TO CATCH IT ON FIRE. I don't need another one of those... Definitely plan to add the homing sensors, limit...

Thanks, I've wondered what the realistic difference is between the 20mm round rails and the linear rails.

You're right, I just need to get it going as it for now.

I reached out to CandCNC,...

Hi all, I'm the new guy I guess. Hoping someone with some experience can give me info about this design. I'd like to find other discussions or documentation about it, if anyone can point me in the...
