Focused on utilizing MatterControl’s 7 and 13 level print leveling? Though, this method is simple to make use of, there is likely to be some {hardware} or firmware settings you may want to repair first. Here is how!

MatterControl just lately launched 7 and 13 level software program print leveling. These are nice choices for delta 3D printers, in addition to Cartesian printers with giant print beds.
Although very straightforward to configure and use, there are some {hardware} and/or firmware settings wanted to ensure that MatterControl’s software program leveling to perform correctly.
There are two primary configurations for 3D printers because it pertains to endstops and leveling – Z Minimal and Z Most. When you have not been in a position to obtain correct leveling with MatterControl, we’ll cowl the options for each sorts.
In an effort to get good leveling outcomes – no matter what sort of printer you might have – the nozzle of your sizzling finish should be capable to pinch a chunk of paper (or feeler gauge) towards the mattress. When you have a machine with a Z Minimal endstop setup – the place the Z endstop triggers on the mattress, Z=0 – it’s potential that one space of the mattress could also be beneath Z=0. Since most Z-Min setups don’t bodily enable motion previous Z=0, this is not going to will let you get good software program leveling outcomes with out some changes. When you have a Z-Max setup, you doubtless have firmware endstops enabled that additionally stop you from contacting the mattress. Happily, each of those points are simply resolvable.
Most Delta printers use a Z Most endstop configuration. This implies the Z axis properties to the highest of the construct envelope, to not the mattress. To stop harm to the print mattress, there are sometimes software program endstops enabled within the firmware. These most frequently are set to not enable the machine to maneuver beneath Z=0, nevertheless it’s additionally widespread for them to be set to a really small unfavourable Z worth.
MatterControl, by default, doesn’t will let you go beneath Z=0, however you may change this setting.
Upon getting allowed Z to be unfavourable, configure the auto leveling by way of MatterControl. Upon completion, click on the pencil icon subsequent to the Automated Print Leveling.
This may open a window displaying the entire sampled positions.
What we’re in search of are any unfavourable Z values. If any of the positions have a unfavourable Z worth, it’s doubtless the firmware will stop correct print leveling.
Should you do have some unfavourable Z values, it’s straightforward to resolve. First, discover the bottom unfavourable Z worth. Let’s suppose the bottom worth you might have is -1.46. We might then want to extend all of the Z values a minimum of 1.46mm with a purpose to get them out of unfavourable vary. So long as we shift all of the Z values the identical quantity, our software program leveling will nonetheless work correctly.
On this case, including 2mm to all Z values will get the whole lot into the optimistic vary, and will probably be a lot faster than including 1.46mm to every worth. You should use the Up/Down arrows in your keyboard to rapidly add/subtract 1mm. So, we might click on on each Z worth – not simply the unfavourable values – and enhance it by 2 mm.
As soon as that is carried out, click on Save within the backside left nook of the window.
We’re not fairly carried out but. The very last thing we have to do is modify our Z peak to account for the 2mm we simply added.
Most firmware on Deltas have the Z peak within the EEPROM.
You may entry EEPROM beneath the Choices tab. Find the Z peak area. On this machine, it’s referred to as Z Max Size.
Improve this worth the identical quantity you elevated the Auto Leveling numbers. Click on Save to EEPROM within the backside left nook. And we’re able to print!
This could resolve any points you’re having with a Z-Max fashion machine and MatterControl Automated Print Leveling.
Acquired a Z-Min setup?
It’s not widespread for Z-Min fashion machines to have points with the auto leveling, however there are 2 choices to resolve this situation.
1) Run Software program Print Leveling. Should you attain an space on the mattress that you’re unable to maneuver Z decrease to appropriately pinch a chunk of paper towards the mattress, modify the peak of your mattress till it reaches the nozzle. If you want to transfer the mattress through the configuration course of, you will want to run it once more as soon as accomplished as different sampled positions may have been affected by the mattress motion.
2) Modify your Z endstop to permit the nozzle to maneuver decrease. Warning: That is solely beneficial on machines that house the Z axis with the nozzle positioned off to the aspect of the mattress. Doing this might enable your nozzle to smash into the glass when the machine properties at the beginning of the configuration course of.
If you’ll be able to correctly transfer the Z axis to pinch a chunk of paper towards the mattress at all the factors within the leveling course of, the software program print leveling provides you with a superbly stage print, whatever the bodily flatness of your print floor.
