Hemera steps per mm8/1/2023 ![]() ![]() The actual thickness of a single perimeter wall printed at 0.20mm layer height should measure be about 0.52mm. Consider the 0.48mm you're using more like a center-to-center spacing of the extrudates, but don’t expect a single wall to be of that exact size. Try 0.42 or 0.45mm.Īlso, since you also changed thermistor and heater, you may want to re-tune your printing temperatures.īut most importantly, using a hollow single perimeter cube is not a good method to calibrate your extrusion multiplier. With an extrusion width of 0.48mm you're amplifying variances in filament diameter. Surely there has to be something wrong with the extruder itself? Am I the only one with poor extrusion quality? ![]() Nothing is loose and I have check all I can. I also checked the other axis just to make sure and they were all spot on as far a moments. There is nothing else to check in my opinion other than maybe a nozzle issue but it was new and came with the Hermes. 90 and will see what that yields but seems like this is viscous circle now and has to be something eitehr mechanical with the extruder or these units just produce rough surface quality which I find unacceptable. 52 but the extrusions are still rough and really no change from the first set of solid cubes. 54mm so it was over extruding a bit still somehow. I did a test print of a hollow 25mm cube with the extrusion on auto in S3D at. ![]() The eteps were close it was a bit under extruded at 393.27 so I went back to 397.24 for it to be spot on. Well went back through it all with the tightened filament tension bar flush with the arm as some have mentioned. I have tried the tension gear loose and about 5 clicks in and now I tightened it until he white part was flush with the arm, which seems really tight, but I have not printed with that yet.Īnyone have the same issue or have any ideas? I have used my same S3D profile and prusa slicer as well with the same results.Ħ. Tried many different settings and all end with the same results regardless of slicer. All the driver gears look fine from what I can see.ĥ. Stock boar with a external driver board for X and Y using 2209 drivers.Ĥ. 525 v on the vref pin on the mini rambo.ģ. I have calibrated the extruder and had to lower the esteps from 409 to 397.23 (i think that was the number) since I was over extruding about 4mm.Ģ. I seem to be getting real inconsistent extrusion horribly similar to the MK3 debacle and the swept under the rug 602 issue.ġ. It was a new build especially for this extruder. I installed the Hermes on my old Mk2 with the bear conversion frame. ![]()
