Replaced LPU cable


Error code 56 and it was diagnosed as a bad LPU cable.
I received the cable Friday and today started on a 18 page
process to remove the LPU and replace it’s cable.
The document was clear and contained many helpful pictures
( 1-2 per page ). The result was success. My form3 is printing.
I have only one complaint., the instructions said 20-30 min. For
me it was more like 90-120 min.

Thanks Formlab


Cool, thanks for sharing! If it’s any consolation, it always takes me longer than their time guidelines, too. Probably just means you’re meticulous.


Where did you get the instructions? It seems like Form doesn’t allow access to those documents unless you go through tech support or your dealer… I used the change LPU command to bring the unit out to clean the rollers. Now I get the bloody 56 error every time. Really wish there were more online resources for troubleshooting…


I got the instructions from Formlabs support.
