So I’m not 100% happy with the default settings in the config file for the leveling-strategy.
I’m trying to move to the ZGrid-leveling solution, but I’m coming across some odd things happening. I need to probe a few more areas than just the 3 that are in the delta-calibration setting, as the areas that are not probed are the ones that seem to be causing the problem.
The problem I’m having is it only seems to probe half my surface from the mid-point back to the Z tower. nothing on the half closer to the X/Y towers. I’m not sure I understand why this is happening. Can anyone provide some insight into this? I’ve attached a video of what I’m experiencing. Thanks in advance, http://www.youtube.com/watch?v=XQxtPtFP2uE
Also, grid levelling is still new on delta machines, you should get the normal delta calibration ( which will be largely sufficient on a glass bed ) to work first before trying grid.
@Alex_Skoruppa I started with the 200 x 200 settings, but the effector would move right off the bed, so I tried shrinking that number.
@Arthur_Wolf I started with the standard delta calibration which worked, but the variances in bed height seemed to be 90 from where the bed was probed: ie: directly between X/Y towers (X0 Y-100) and so-on.
Mabye there’s settings I’m missing in the delta calibration that would help?
I think I’m going to switch to FSRs pretty soon here.
As for the bed, it’s a heated PCB with a 3mm borosilicate glass top. I’ve checked it with a straight-edge when the bed’s at temperature, its not terribly warped, just the bow is where the probe doesn’t touch.
I’m running a version of smoothie-edge - it’s on an X5. I will upgrade if you need me to. lol Just tell me what to do. I’d love to get the grid working!!
I do not think zgrid works on deltas yet. ask @Quentin_Harley he wrote it.
You do need to tell it that the 0,0 is the center of the bed not the front left corner.
