I installed the Hermes on my old Mk2 with the bear conversion frame. It was a new build especially for this extruder. I seem to be getting real inconsistent extrusion horribly similar to the MK3 debacle and the swept under the rug 602 issue. 1. 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. 2. I have edited the firmware and have .525 v on the vref pin on the mini rambo. 3. Stock boar with a external driver board for X and Y using 2209 drivers. 4. All the driver gears look fine from what I can see. 5. Tried many different settings and all end with the same results regardless of slicer. I have used my same S3D profile and prusa slicer as well with the same results. 6. 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. Anyone have the same issue or have any ideas?
