Re: Standalone controller V4.0

Thanks, dragonator. I will do one last thing. I will connect my V4 controller jig to the gantry of the printer (I would just connect it), i.e. it will own the same power conditions as V3 that is already mounted. If then V4 fails to prime it, I would believe that this is related to input voltage, but...

Re: Standalone controller V4.0

dragonator, but the problems now is that V4 controller (with inkjet commander) actually primes and tests (300/300) fine both HP heads: with my custom binder and neat HP4 with black ink. Whereas V3 controller (which used to print before and worked) primes well neat HP45 head (original black ink), but...

Re: Standalone controller V4.0

V3 controller works fine, I have printed with it before and it does prime well with black ink already. I have been using it multiple times. I made V4 controller as a helping jig to test binders and this time, binder sprays with V4 controller, but does not spray with V3. V3 controller is the last ver...

Re: Standalone controller V4.0

dragonator, I have been recently using V4.0 controller with inkjet commander slightly. Since you said that V4.0 software cannot print yet (with encoder tape), I decided to make one and use it as a testing jig for HP45 binders (basically to test if nozzles spray binder). That jig consists of RPI3 + V...

Re: Hacking the Xaar 128 printhead

Hi, kulhom. I have been recently trying to come up with my one ink/binder formulas for printing. I am more fascinated with inks rather than powders, because those are more or less commodity and not that much can be done there to improve things. But I really find it difficult to make something reason...

Re: Hacking the HP45

That shift is only when printing. I double checked and it is good in preview window. Is there anything I can do to help you finding the reasons? For now, this is not deal breaker for me as I am just starting printing and getting at least something printed, so such shifts are not huge problem, but if...

Re: Hacking the HP45

Dear, Yvo. Do you have any ideas, why such shift can occur? At the moment, this is with V3.02 driver. I have not changed it to V4 yet as I tested V3.02 and wanted to try that one first. Interesting, but this shift happens randomly and it might occur for one layer, but others can continue normally. T...

Re: Standalone controller V4.0

But could it really be resistor from driver, when another HP45 shows correct temperature? I assume that with PCB itself it should be OK, shouldn't it? With all other heads that reading is fine. But it is really weird that this number for some reason is missing and it is still working... Because driv...

Re: Standalone controller V4.0

Dear, Yvo. I was wondering, perhaps you know the reason. With controller 3.02 (that was the latest version?), I noticed that I get current HP45 temperature -0.2C all the time (in Oasis controller). However head works fine, prints well, all nozzles pass the test and it seems to be working fine, but t...

Re: Empiric 3000 3DP printer

Right on track. I have installed additional heating to build piston to (potentially) easy post-processing and reduce wait times before one can dig the part out. This additional heating is targeted towards gypsum and other simple materials that use water-based and other easier binders. During printin...
