Re: Resin pigments

How are you paying through the nose for Resin? You guys actually have 2 dealers that charge close to the going rate. Canada has no dealers, we get hammered with high shipping and customs so count yourself lucky. ;) http://www.gizmo3dprinters.com.au/ https://www.bilbycnc.com.au/MakerJuice.asp

Re: Nema 17 slipping

What are your stepper motor specs? Have you adjusted your stepper driver properly?

Re: Regular Band Pattern on Surfaces

I can verify this indeed does help. Slicing takes longer of course, but I had significantly fewer bands across my part with this and all of the CPU spikes are now gone. I had maybe 1 band on a 2" part printed @ 0.1mm layer height. This is down from ~12 for that same print, when generating the ...

Re: vat coating sticking on printed part

Looks like your printing straight up, you can't really do that on silicone VAT coating unless you move to a new spot once you have burnt the area your previous print was at. What is your layer height at that exposure? If your at 100 micron or less your over curing your resin and it may be burning in...

Re: multiple projectors

IMO and this is just from printing in the last 4-5 months a large VAT/print area is just going to give more issues than it's worth. If you want to print large objects FFD printers are far better options, I have 2 Deltabot prints and one Makerbot and they all print nice large pieces far easier and c...

Re: Regular Band Pattern on Surfaces

Thanks for the input Finhead. I'm going to build a flex bottom. I thought a passive tilt would be good, but it still takes a surprising amount of load to release the parts from it. Which version of CW did you find works properly? I'm using the newest one and I wonder if I am getting different cure ...

Re: Regular Band Pattern on Surfaces

The "nut" is two brass nuts with a spring perched on a flange between them. I should be able to try back mounting my screw fairly easily. Running a test with dial indicator right now to see if I can narrow down what's going on. Edit: My measuring rig is not rigid enough to withstand the s...

Re: Flex bottom VAT

HP yeah I agree the indents mean nothing just wanted to mention the only down side of this set up since people have asked. :) I really think this is the way to go with VATS for this kind of printing, I cannot see any disadvantages and peel is so smooth and no messing with silicone or dry times. Supe...

Re: Regular Band Pattern on Surfaces

The linear part of your Z is nice, square rail linear bearing. But your using a threaded rod with what nut? The problem I can see is your side loading the bearing in your configuration so if you have any play in the lead screw (which you will if it's a threaded rod) your pulling bearing forward and ...
