Firmware v1.1.8 not usable

Post by e415ldc » Thu Jul 11, 2019 5:28 am

I have two i3 Pro c printers. One uses the old GT2560A board and the other uses the GT2560A+ board.

I have recently down loaded the new 1.1.8 Marlin code and have attempted to get it to work with both boards. It appears the code is written specifically for the A+ board as the 3D Tough pins are not properly accounted for in the PINS files. That is another issue.

My issue is -- Once I get the code loaded all is fine when controlling the printer via the control panel. Auto bed leveling with my 3D-Touch works great1

Once i slice my test object with Slicer and then try to print it with Repetier, things go very wrong. All is fine during the homing and bed leveling (G28 and G29). After that the printer slams Y carriag all the way forward and the X carriage all the way to the left. My only option is to hit reset.

Has anyone gotten the new Marlin 1.1.8 to work with a 3D-Touch on an Acrylic i3 Pro C?

Now I'm confused even more.....

The current firmware listed for the i3Pro-C is 1.1.8 as per these extracted lines:

6) Firmware for I3 pro C
Update:
Fixed the endstop error(Default endstop logic status is the"false")
2019/2/27
Marlin 1.1.8 for proC with GT2560VA/A+/2.0
1.Inculde 3dtouch config and no 3dtouch cofing
2.Added the new menu for extruder+hotend

I have 1.1.8 on my Pro C, and..

My i3 Pro C running Marlin 1.1.8. on a GT2560 Rev A. Things are moving MUCH better now. But, I have run into a problem with the Z Axis.

When Z Steps_Per_Unit = 1280 The z moves nice and smooth. But only half the distance ie. 10mm of indication = 5mm of movement

When Z Steps_Per_Unit = 2560 The z buzzes and hums. IT only moves, when I help spin the lead screw, and even then it only moves a fraction of a turn then stops and hums again.

Both Z drivers vref are set to 1.04v. I have tried them from .5-1.1v. with no change.

Now.... with one of the steppers disconnected... the other stepper will move without issue when Z Steps_per_Unit is set to 2560...

Any idea?

That link is to a Hex file, not a Marlin / Arduino download. perhaps for an other board?

The link I used got me exactly what I would expect for Marlin code and the files match the description as well.

As for the Z axis issue. i found the steps were 10 times faster than they should be. I think there is a bad line related to calculating the mm/second. I set mine to 1/10 what it would normally be and all axis' work fine via the control console.

All I found was a .hex file, but I have installed new steppers, and THAT helped with 1.1.8 on my GT2560 Rev A.

hi,That link is to a Hex file Is to convert the firmware to a hex file

hi,
in the firmware the Z Steps_Per_Unit = 400,Why have you changed?

I haven't changed steps per unit. I have changed mm per second/minute. The stepping rate is too high and that is/was the source of the buzzing sound and lack of movement.

I'm thinking the setting is supposed to be mm/second and it is set for mm/minute. if the printer can achieve 10mm/second that would be 600 mm/minute. So if someone placed the 600 as the mm/sec, the speed would be 60 times what it should be and the motors/drivers just can't go that fast. The buzz i heard was a very high pitched squeal. I'd had worked with stepping motors in my job in the military and tuning them past their rated stepping speed sounded a lot like this with the motor just vibrating causing the squeal. They sometimes ran backwards with no strength as well.
