Same issue and worse support!?

Sorry to hear that. I suggest a phone call and a request to speak to a tier-2 tech. Their folks who deal with email are not really that technical.

However, if you want to address this yourself then I suggest you do what I did: Manually level and turn off auto-leveling.

The original Robo with it large bed had significant improvement in ease of use from auto-leveling. That bed is so large and difficult level effectively that it was a no-brainer (and even now MESH helps account for inconsistencies across that rather large chunk of glass).

The C2 is not that way and it is pretty easy to manually level it Once you have done that you just stop sending it the G29 in the startup.

I personally and going to upgrade to Marlin 1.10 when it officially releases and test MESH leveling on the C2 and may well keep that, but the old-style ABL is not really needed on the C2 and eliminating that makes prints start faster too.

 

With the old Robo your manual leveling "controls" were the 4 posts on the bed corners and that was essentially all you could use to tweak the level. On a bed that size it was not always effective. On the (approximately) 5" bed the C2 has it is more than enough to get the job done as long as your plate is not seriously bent.

 

That is where it is setting the Z height for the little "line" they draw across the front of the bed to prime the nozzle just before starting the print.

@colton81 buy the magnets anyway, in various sizes, they are good for a multitude of projects. Use them in your 3D prints to make models that need to be opened or come apart regularly. eBay or China. I usually buy assorted sizes at 50 to 100 at a time and use them all over the house.

 

Excellent news. I am glad to see that they are willing to take care of this. Given how hard it was to get a replacement unit (as opposed to them shipping you replacement parts) with the R1 series, there is no way the C2/R2 simply could not manage with that approach. It is an integral part of making your product into more of an 'appliance' that end-user repairs will largely go away.

There is still opportunity to hack, expand, etc on the new ones, but that is not the target market they are aiming for.
