I bought my PRTAlpha 48 x 96 w/ the new 7.2 gear boxes last Novemeber and I just completed assembly. It appears that my unit values are not set correctly (I tell it to move 10" and it moves just over 5") I counted the gear teeth XY = 28 (gear stamp EN 6412)I can not count the Z gear teeth (gear stamp EN 6403). My unit values are at default for the PRTAlpha and I need to know the correct values. I've been searching for hours and can not find this combination. Any help would be greatly appreciated.

Thank you,
Randy

I just pulled one of the x motors off to verify...30 tooth gear & 25 on the z. I think I have it. Found the UV's from an old post.

Randy,

I see my nearest "neighbor" is now under 30 miles. Welcome to the club.

I am a new to my shop bot, but if I understand your question correctly it is 2482.8171 for the x and y. I have a PRTalpha 48 x 96. I have the 7.2 gear boxes. Hope this helped.
