having issues with z mapping
-
hi,
I'm fairly new to RepRap and I'm having issues with my printer wanting to run at the top of my z axis and not an z home here are my files if they help. any help would be appreciated

Can you describe the problem in a bit more detail? I'm not sure what you mean by this.
Also please upload your config.g file. The config.json file is meant for the online config tool and is not human readable. It also doesn't reflect what your config.g is right now if you've manually changed it.

config.g here ya go and thanks for the help. I'm running a Cartesian with all axes are homing correctly but when i try to print it moves to the very top of my machine and stalls out like its trying to fun at 400mm instead of at 0 if that makes sense to you my machine is 300x300x400

Hi,
In the future if you could copy-and-paste your files using the </> tag it makes it easier for all to read without having to download.
When you click the </> in the toolbar you will get an opening line of three accent characters, a line saying undefined and then a closing line of three accent characters.
You replace undefined with your pasted code.
I have done so below with your config.g file so you can see how it works.

In your M208 commands your Z min is set to 400 and your Z max is set to 800.
I think you want that to be Z min of 0 and Z max of 400.

sorry sent the wrong cofig file that was me trying to figure out the issue but its the same but 0min and 400 max but it still is doing the same. do you want to see the other config file? thanks for the help I'm new to RepRap
-
would it be my g92?
how do i change it -
@kevinlallshouse said in having issues with z mapping:
would it be my g92?
how do i change itWell that G92 is saying Z is at 800 when it is likely nearer 400.
The point of the G92 is to adjust for where the endstop actually triggers.
A G1 H1 Z499 command would move until the endstop triggers. At the point the Z logical position would be set to Z max as set in your M208.
But suppose your Z endstop actually triggers at 395. In that case you would use G92 Z395 so the logical position (where the firmware thinks Z is) would match the physical position (where the endstop actually triggered).
However you may want to move your Z endstop (if possible) to trigger at the Z min end of the axis, which will save time when homing Z.
Frederick
-
+Z should move the nozzle and bed farther apart.
-Z should move them closer together.Is this how it is on your printer?
You currently have it configured for a Z max endstop, meaning the endstop is at the farthest point away from the bed. Is that actually the case?
-
ok my Endstop is at min. z axis not my max z axis and yes its 400mm not 800mm can I change this in RepRap configurator?
-
You could reload your config.json file into the online tool and make your changes and then save the new set of files, that may be easiest since it would require changes to the endstop definition, and your homing files to get everything going in the correct direction. It may or may not also require a change to the motor direction.
All of this can be done manually by editing your existing files as well. The config tool gives a good starting point, but eventually most people will begin editing the files directly.
The endstop change for instance, This:
M574 Z2 S1 P"!zstop"
would become this:
M574 Z1 S1 P"!zstop"
Z1 means low end of travel. Z2 means high end of travel.For the homing file changes, this:
G1 H1 Z405 F360 ; move Z up stopping at the endstop G90 ; absolute positioning G92 Z800 ; set Z position to axis maximum (you may want to adjust this)would become this:
G1 H1 Z-405 F360 ; move Z up stopping at the endstopZ405 is positive upward movement, Z-405 is negative downward movement.

ok ill give it a shot and thanks for all your help and taking the time to explain everything.

here is my homez i dont see anything wrong my z is a -400 like you had said do you see anything with it ?ill post others next

That looks better. Does it home in the right direction towards the endstop now?
-
@phaedrux yes everything seems to be working now after your help so thank you all for taking so much time to walk me thru it.
-
@phaedrux one last thing if you don't mind. my heat bed is faulting out because it is not heating fast enough i think it said with in 1.3 c a sec. my question is would it be ok to disable that or make it for a longer window to allow to heat? any guidance?
