We think the problem is inside the cartridges, but can’t seem to resolve the issue. So there should be no flow problems present at the moment.

Now there is actually too much binder dripping out of the septum, but if the cartridge is inserted it stops and should provide more than enough flow to meet the requirements of purging and printing. disassembling everything and checking for flow problems. Our goal is to print with sawdust just like you Scott, it would be amazing and cheap and we could use those parts for so many things!įirst, there was actual organic junk in the binder tubing which we cleared out, used some alcohol etc. Lately we have been trying to repair a zPrinter 310+ in the shop and although we found a few problems we are still struggling!

This is usually enough to ‘purge out’ the pigment based black ink, and flow in the dye based yellowĪfter that, I can reliably print in sake.

Push 30ml of yellow ink into the septum with the purge kit, filling the binder lines.

Select ‘install new head’ via the ‘N’ command from the console - and NOT via the Z-Print application.

I keep a supply of ‘bulk refill’ dye-based yellow HP10 ink ($20 from ebay for 250ml) on hand to do purges with. I replaced that connector, and my heads no longer burn out, and I get much better saturation. You can determine if you have this problem if ‘pushing’ binder into the septum using the purge kit syringe is much easier that ‘pulling’ binder via the syringe. The snap-fit binder line connector on the back of the fast axis has a one-way valve that degraded over time, and wouldn’t let binder flow to the head at more that a slow dribble. Pre-flushing the printhead with a dye-based ink resolved this issue for me. These particles clogged the mesh filter, and the printhead nozzles themselves. Turns out that the sake I was using chemically combined with the pigments in the black ink, and the pigment particles flocked into large particles. has it in 7lb buckets, if I can’t find a local supplier.Īs for the HP10 heads - I was getting similar burn-out issues turns out it I had two issues - a clogged binder line, and ‘flocking’ in the cartridge.ĭisassembling some ‘dead’ HP10 printheads, I was surprised to find that the fine mesh filter over the inkjets was clogged with a black sludge. Looking at other USG products, I’m thinking about running some USG DryStone in my Z310+ - it requires less water than HydroPerm or UltraCal 30 to set.
