Agreed, extrusion looks OK it has to be the Z-steps. Paste your configuration file EEPROM settings. Here is mine, however I have stock 8mm x 1.25mm stainless (straight) z-axis threaded rods.Dim3nsioneer wrote:I think the steps per mm on the z axis are wrong. Nothing a M92 can't fix.

I found out that you can extract the default EEPROM values using Repetier Host program and having it load the EEPROM data so you can record it pror to re-flashing the board. I _think_ it works with EEPROM not enabled.blc wrote:I wish I'd known about the firmware backup before now. I don't know that much about firmware settings, but I know that this isn't right
That's supposed to be a 20mm cube, before I aborted the print. I get the same results in both Cura and Slic3r, and it's pretty much the same on both RC4 and RC5.
It seems to extrude just fine, so I don't think I've got a blockage. Any idea where I should start with this?
You are more than welcome and very glad that a fellow HICi3 user is doing better!NotMe999 wrote:Chip,
Thanks for the firmware. With your settings and a couple changes for my machine (like z-axis, 398 works fine on mine), it's printing out nice objects now. My only problem is some stinging across open spaces (much less than before the new firmware). I think I have it down to hot end temp or e-steps. Just gotta have the time to nail it down now.

No problem glad to be of help. Remember, set your speeds low BEFORE calibration for now. If you do not, you will wind up starting calibration all over again, trust me:blc wrote: Apologies I haven't replied sooner...
I managed to work out that my steps per mm on the z-axis should be 400 and so far this is looking perfect. Yeah... So I need to learn how to calibrate my 3D printer...
When I get some time this week I'll take a look through the two links you posted, Chip.
Many thanks for all the help!
