It had been quite a long while I've posted anything. I've wanted to get back to the shop to do some work but many things demanded my attention.
A dear friend of mine, Terence, helped me recently to look at getting the Portabee working properly again. He did some tweaks, uploaded Marlin onto the board, and help calibrating it. The result he managed to get out of the DIY printer is commendable:
The printer was sent back to me few days ago. As I was rather busy, playing with it started only late today.
Not wanting to disturb anything, I plunged into printing the adjustable endstop after keying in all the settings Terence sent. The first print was nothing short of a disaster, which I later realized that I missed out the retract checkbox... Can't even follow instruction... Lol.
Here are the ruins:
With the retract enabled, I printed the 25mm calibration cube downloaded from Thingiverse as suggested by Terence.
The print came out alright though I prefer better resolution.
Here are the pix of the cube:
I measured the sides with my trusty Mitsutoyo Digital Caliper:
X and Y are a little oversized. Z is a little under. Terence suggested doing another print to confirm the result before any adjustments.
Oh, I forgot to mention; I lowered the print speed to 60mm/s when I saw the flow of plastic not catching up with the axes movements.
Test will resume another day. Full day of meeting tomorrow.
