Build Your Own SLA/SLS

It looks like it'll work. I don't know why people keep opting to push the fep down when the opposite seems more logical. Doing the inverse keeps the vat bottom almost at the same height of the original petri dish and the pushing force is done upwards so by pushing it down when the z-arm lifts the fe...

I'm using just 1.5 anti aliasing in the settings.

Building is finished, here are my first prints. I'm using a home made first surface mirror so quality might get better with the one I bought from Brad. I'm using Spot A GP resin, the mix for the B9 and results are encouraging so far. I had some problems with base adhesion and I'm working on that rig...

A bit offtopic, I did the mod on my P1283 and thought it wouldn't be that hard to come up with a mechanism where you move the lens in and out by 3mm, I'm only using mine for 3D printing but if I needed it for other applications I would have done just that.

Solved this one the hard way, rewired the motor and it's now working perfectly. I don't know if the original inversion was due to the A4988 or a "inverted" cable, all I know is that once I rewired the motor everything went fine.

I don't know if it's relevant but I'm using the stepper A4988.

I already changed $7=255 in GRBL to $7=128 (Invert mask) but nothing changed

Hi there, I did my modifications on the Acer P1283 yesterday but I have some questions I already put the M4 spacers in the lens and now I can focus in the vat easily. Should remove the UV filter? Also, when I move the lens assembly forward 3mm the zoom screw/ring only moves a little bit (4mm) to eac...

So as I told before the littleRP clone is built and I'm doing the last adjustments, it was when I noticed Z axis is inverted. I built everything according to the Brad's instructions and when I go to creation workshop controls the Z axis movement is inverted, when I press for the Z to go up it goes d...

I was precisely investigating this option, will try it tomorrow. Thanks.

Everything put together, software installed and hardware ready, only the resin is missing! Unfortunately there's still one issue to adress, I have ghosts on the image projected in the vat. There's the main image an then there's 3 or 4 other images! I bought the mirror at a speciality house, it's a r...
