Evidently version 3.7 is not completely compatible with firmware in printer.

Note: I won't be posting here again until changes are made at this website

Have Fun Guys ! I'm Gone !

You've said that before, don't make promises you have no intentions of keeping.

I guess that's up to you, continuing to think that for some reason your machine is unique to the world of 3dprinting has yielded nothing.  Perhaps it's time to take advice from those of us with more experience than yourself.  The problems (and they are numerous) you are having have little to do with the quality of the softwares you are using.  The answer to your "stair stepping" problem is simple and most of us have the solution.  But as long as you (or the group of you) refuse to do anything in the way of helping us help you, don't expect the answer.  I find it difficult to believe there is only one user behind this user name as well.  Although I am not aware of any rule that prohibits multiple users utilizing one username I think it's about time we put one in place.  I have followed every one of your posts since the day you registered and have been skeptical since day one.
When you finally decide you truly want help it may be too late.
3dprinting has a very steep learning curve for all of us.  We've all made really stupid mistakes and made our own luck.  What sets you apart from most users has been your ability to constantly get in your own way.
I would have preferred you simply state that you don't have the understanding or ability to post a picture.

I gave up on him/them as well Ward. He is not even willing to except input from someone who has the same printer and thst has dissected it down to firmware level. He is convinced the printer itself cannot be the problem when I found a host of issues with my higher model.

How's that picture coming along?

Sorry, but I'm not going to Waste filament just to get a picture, of a failed print,
by going back to those settings, that I sometimes prefer, but for most objects are Not necessary.
(like 4 shells instead of 3, and Higher % infill)

I'm now working on ways to 'improve and solve' the problem.
I'm now sure that finding Better or more Compatible host/slicer software is the Only way to do that.

When and if it happens again, I Will get a picture tho !

So, I'm still looking, if anyone knows of 'Good' host/slicer software,
that will work with CTC printer ??

Since the problem is definitely in the slicer software.
And I don't think I can change the Slicer in Makerbot-3.7 ?

Maybe I've missed it, but have you ever posted a picture of the "stair stepping" affect?

No, but I would be Glad to, next time it happens,
if you think that will Help solve the problem ??

Not much to see though, filament is normal at one side of object
and laying Loose at other side, since that side has no first layers

the print I did this morning only had 1 step, so it was acceptable,
it had 3 steps before I reduced shells.

Note: I checked trash to see if any were still there but all have been discarded

By reducing the complexity of the print,
Like reducing wall thickness layers (shells) and reducing Infill percentage

the slicer must not be allocating enough memory space, or something like that ??

Note: reducing shells from 4 to 3 greatly reduced the problem
