correct... i get no response of any kind when using the FW that folger tech says to use... however it works with marlin 1.0.2 thats currently running my mendel90... display or no display, makes no difference...tried pronterface, repetier, and octoprint, and my normal choice mattercontrol...i even call matterhacker to see if it was the controller and they said its the FW...

Ah I see what you are saying now. So the acrylic that I have my print bed attached to in this picture I should change to something different and more solid?

I used longer screws to hold the hot bed to the acrylic, with a stack of O rings. Changed it to 3 points of attachment instead of 4, much easier to align.
Then cut a piece of glass to lay on the AL hot bed, held in place with a few binder clips. No more worries of a convex bed. Cheap and simple, still use the blue painter tape on the glass and PLA sticks just fine.

baudrate at 250000..serial 0... it all registers just fine on the pc on COM3 as Arduino Mega2560...
i just got a FW DL from forum member pazza that hes using on his revision B printer... same as mine.. but his works... ill test in the morning..its 1am here...
strange how it works with marlin 1.0.2 but not the FW directly from FT

Rick, I'm going to have to do something because this print bed is really giving me an issue because of the warped convex shape. How long does it take
For your glass bed take to heat up when you print?
Would out be easier to replace this print bed? Does anyone know of a quality print bed I can buy that would be an easy replacement for this one?

Seems like your delta radius is off.
Have you done the flatness calibration?
Before you do it, you should try to get your bed as level as possible, I used a right angle, and put washers under the mounts to get it as level as possible.
- Check that the nozzle touches the bed at the same z-height at all three towers + center.
If center is higher, you need to increase #Delta_smooth_rod_offset if i remember correctly.
To get the towers the same height, you can move the endstops, either physically or in firmware. I did it physically, so I don't know how to do it in FW.
And the delta dimensions from folger is inncorrect! I had to measure my printer, enter them into the firmware and recalibrate to get the xy dimensions correct.
Here's a guide: [builda3dprinter.eu]

Try to level it out with mallet if you have one. But be careful too. I saw someone here did it and it worked for them.

I am late to the party, but was wondering if anyone else had to reverse the motor plugs from what is in the folger documentation? also, how do you disable the auto bed leveling for the kossel rev b?

Just dont use the G29 code and it wont auto level. It does not run the auto level automatically.

Ok, thanks for the response! Am I correct regarding the motor wire orientation?

I have the Rev B. with the inductive proximity sensor. I can home with G28 fine, but when I try the G29 to probe the bed, it moves down to about 30mm above the bed then "dances" up and tries to crash through the endstops???? Any help would be greatly appreciated....

davidf01, have you tried to do the bed leveling calibration with the bed at temp ? i had a similar issue with my mendel90 and a cheapo aluminum HB... as it warmed up it warped in the center, so i did a calibration while hot and just did all my prints with the bed on...works perfectly.. for me anyway... just a thought

09zx-6r,
Yes I have calibrated with a hot bed and a hot nozzle. It does help a little bit but not enough to over come all of the bulge. I think it is just a really strange
plate that may have been a little off when they cut it. Thank for the input, every little but helps.

This is pure and simple thermodynamics and mechanical properties of what you are dealing with. The aluminum most likely was not "miscut" even thick ass brake rotors warp while sitting on the shelf waiting for customers to purchase them. The plate has solder points in the middle, when you rest a stack together the ones in the middle will bend due to the weight from above. Add to that the PCB heating up and causing an additional warping issue. I corrected the bulge in my plate by mounting it to a hard surface by the bolts and knocked it in the center with a rubber mallet. This flattened the curve out, I then mounted it to the printer onto the larger aluminum plate to try and prevent further warping. If you want to eliminate the bulge and get pure flatness, switch to glass and a polyamid heater with adhesive on it, like these here.
