[BUG] Z = 1 after G28 on delta #15495

Closed Glodigit closed 4 years ago

Glodigit commented 4 years ago

I git pulled the latest 2.0 and after G28 on my delta, the Z height is set to 1mm instead of the delta height.

Steps to Reproduce

  1. Pull latest marlin
  2. Send G28

Strange because I came on here because I have the same problem except my Z = 5 been using ver 2 successfully for 2 weeks but now has developed this problem

Glodigit commented 4 years ago

Ok I've determined that the Z is correct when bed levelling is turned "Off". When it is turned back on again and auto homed, Z = 1 again.

Seems to be the same issue as #15494 You could try the dev-2.1.x version.

Glodigit commented 4 years ago

Updated to dev 2.1 with the same issues.

I have the same problem after bed leveling. When I start printing, runs G28 and G29, but after Z axis not moving, it's only Z=5 over the bed and prints only at this height.

RMN9 commented 4 years ago

If we i #define AUTO_BEDLEVELINGLINEAR G28 give Z 10 and then G29 give Z 10->1mm

If we i #define AUTO_BEDLEVELINGBILINEAR G28 give Z 10 and then G29 give Z 10

Plugged into MatterControl, I get X: -0.34 Y: -0.22 Z:1.00 with bed leveling on. With it off, I get X:0, Y:0, Z:230.94

Glodigit commented 4 years ago

Looks like there's a sync_plan_position that causes the values to change.

I have the same problem on prusa like printer. The problem is in "void Planner::apply_leveling(xyz_pos_t &raw)" in planner.cpp and concerns only ABL_PLANAR levelling (in my case 3 point levelling). Function "apply_rotation_xyz(bed_level_matrix, d.x, d.y, raw.z);" always returns Z = 1.0

Glodigit commented 4 years ago

15610 seems to work. Now I need to get my TMC5160 to extrude so that I can see if bed levelling is applied.

Evgeny-SPB commented 4 years ago

Issue is probably solved with PR #15636, which is already merged.
