Also if you have play in your YHD-101 Z-Axis at the shaft you can adjust the center roller to fix it!

Is there a need to calibrate the build plate to align flat on the vat just like other 3d printers?

Hallo,

@ Chabo, do you have problems with heat? I thought about using a 100W LED for faster printing but I am not sure about heat which can destroy the LCD.

Regards

Cabo

I have tested the heat with leaving it run for 2 mins. I could feel the heat with my hands on the lcd, my guess is that don't go higher than 50W. This is by no means an accurate measurement of the heat, but I think there are no problems with my current setup. Done a print running for a few hours with 5 sec layer times without any issues.

Custom grid printed with the same settings using an image mask. It's nowhere near 100% accurate but the grid is even and I only have problems in the corners which is acceptable for me. The grid has small pins on every crossing and all of them printed fine.

I accidentally poured water to clean the resin tank. There was resin debris. Is it washable with isopropyl 90% alcohol? :cry:

Hi Cabo,

really great to see your experiment, reducing exposure time to 5 seconds per layer is already a great thing!!

cheers,

Hey Cabo,

Great to see the results ! Very encouraging !

..and I agree, unusable corners is expected and do not matter.

I'll take apart my printer and have a look at what LED I have...heard they upgraded the design a month or so before I bought.

Have a feeling I'll eventually upgrade both led and z axis...but wellsee.
