honestly I don’t understand if you are mocking me or what.
yes, Mark, Cura is a great piece of software made for FDM printers. We extensively talked about it. You might be happy with it and for many applications it is more than enough, but if you need really high quality, detailed and small models it just doesn’t work, and it’s alarming that you don’t acknowledge that.
This is what happens if you print with the Moai small geometric models.
It’s not my machine, others have printed that model with the same results. Using different slicers yields different results, so it’s definitely something happening at the slicer level. We printed the same model with formware too and the issue is still there just slightly better. I feel the problem is a combination of slicer rounding up error and the moai controller which has a 12bit DAC. Would be nice to know how many decimals the moai supports, being 12bit I suspect it only supports 2 decimal precision. So possibly no matter how hard we try we will always hit a wall at the controller level.
You are clearly more interested in bigger prints (moai 200) than in improving the quality. That is totally fine, it’s your machine, your business model. But totally ignoring the problem and saying that Cura is “good enough” is rather irritating… Also considering that the little quality boost all the community is experiencing today it is become @Keowa and I (ie: users, not peopoly) put time and effort in optimizing Curaengine. Gosh, if it wasn’t for the hours of testing I put in the moai we would still be printing at 50um layer height that the stepper drivers on the moai don’t support! @Iakouben and I (again community, not peopoly) recently found out that the drivers can’t do microstepping, so we are limited to whatever the motor (1.9°) and the leadscrew can do (which is 0.02 steps).
Since we are at it. Let’s talk about the Z-axis. Please, release an updated version with dual rail, possibly a ballscrew, but that would be marginal since the controller can’t do microstepping. The community has clearly demostrated that we need better stability to get decent layer consistency.
