My printer prints correctly but it takes it 30% more time to print compared to the expected printing time.
Is there something that would explain that it slows down ?
Should I lubricate the Z Axis ?
Thank you for your help,
Your printer is not faulty and there’s nothing you can do about it. It’s a known issue :
After a job prints, it would be nice if the estimated print time that is shown on the machine could be updated to use the actual print time. This way, re-running a job from the machine would show a more accurate time estimate, which I have found can vary pretty dramatically on long prints.
I just finished a job where the estimate was off by several hours (took about 25% longer than estimated) Since I know it will be used again at some point, but likely not for a while, having the information …
Am I the only one that notices that PreForm is pretty bad at calculating the print time for a build for the Form2 but pretty good at calculating it for the Form1+ ? Form2 calculation is typically 1 hour less than actual on the Form2 but pretty much right on for the same build on a Form1+. That is to say, the calculation is the same either way but the Form2 consistently takes longer to build.
So my company started another round of printing 2 days ago. I printed two pieces and they came out fine, and almost exactly the right amount of time Preformed claimed. One was 7 hrs, other was 3 hrs. So I loaded up my last and biggest piece, it said 17hrs. That kinda blew my mind because I had printed that piece before, and save for a few minor changes…it’s the same piece. This was on version 2.7.x. I contacted support to ask them what could be causing the difference…last time I printed t…
It’s good to talk about it again though, I think we’d all want this accuracy issue to be resolved
Thanks for the information, so my printer isn’t slowing down ?
It would be a software issue ?
Yes, Formlabs seems to be having issues with accurately predicting the print time. For now we can only assume it’s a software issue in preform, as there is nothing pointing toward the printer itself… I mean no one that I know of bothered to run and time identical prints on different printers.
I am not certain but I think the miscalculation of print time might be due to the checking of resin level and refill procedure. My guess is that this is not taken into account when calculating print time.
