adam1mc,
You'll notice that I also had a Skeinforge question that went unanswered. I don't know why.

I am not an expert in Sheinforge but I liked you tabulation of your settings. I had success with printing a 5 X 2 compartment tray tray so I pulled it up and looked at the Skeinforge setting and compared them to yours.

I'm sorry that the table I downloaded didn't format as well as yours did. But you will notice the first number for each item is you value and the second is the one I used. I hope this helps you.

By-the-way, perhaps you can answer my original question:

I had a problem with the cover fitting the twisted bottle. Someone suggested that I "change the offset from your edges in Skeinforge". Where is "offset" in Skeinforge? I am in the "Generate Code" and then "Edit".

Thank you so much for posting your settings. Your Speed > Feedrate is way different than mine. I'll try bumping that up.

These settings are all a little too confusing.

I've been reading Dave Durant's blog and he says that FeedRate is the speed at which the platform moves.

However, I set the 11.42 number by following another Makerbot blog post which had advised me to raise the platform 100mm and then run filament through the nozzle while calculating the time that it takes for the filament to arrive to the platform. Do that 10 times and come up with the average and then that will be the feed rate.

So I'm not sure if I entered that number into the incorrect field or not and I'm a little baffled by what exactly I'm supposed to put where.

Unfortunately, I am unable to assist with the offset question. I've never seen that setting. Are you sure he wasn't advising you to print the piece off center? I really have no idea. I'm sorry. But thanks for your help.

Skeinforge is an extremely powerful software that exists in many versions so it gets exponensially complex as you guys can see. I for one am still using Skein 35 with my TOM and only use the print-o-matic in RepG or SFACTS in Pronterface with SK41 on Prusa (similar idea).

I would venture that is the case of most readers here and why you are not get immediate answers to your doubts. That s the reason i have not offered to help as i probably am less versed on it than the two of you.

Your dialog certainly is going to help others so keep it going and share you progress.

"Few are brave enough to dwell on the infamous Skeinforge dungeons!!!"

Thanks Bluemetal for your comments.
I'm using ReplicatorG 0025 with Skeinforge 35 in my TOM.
The reason I took a chance and answered adam1mc because he produced a neat tabulation of the Skeinforge settings. I believe that many times there are more than one setting that is off when there is a problem. The way he presented his settings made it easy (well, somewhat easy) to compare with mine. I'm not sure if he has found the problem but it's a start.

Thanks for the responses.

I'm still sitting here printing with various changes. I can get the little green man to print out in about 30 minutes with my feed rate set around the 11.42 mark. I tried the 24 setting that was mentioned above. When I did, the motor speed (RPM) went way up. But regardless, the faster speed made it harder for the filament to adhere to the platform. I've kicked back to the 11.42 mark and I'm going to keep trying using some of the variations posted above.

Plus, I've enabled/disabled some modules per Dave Durants suggestions. So we'll see…..

If anyone feels like printing the same model and then posting a picture so that resolutions can be compared — I think that would be great!

Here is my Little Green Man.

I know, I know he’s red, maybe from a different planet.
He does look like an Egyptian Mummy. I printed this with all the settings I gave you except that the raft was used. During the work I’ve related to your project I noticed that my HBP was slightly tipped. So I reset it. This resulted in the raft being smushed (a technical term) down. I’ll fix that by re-calibrating my Z-axis travel.

That's awesome. Thank you!

Your face is a little more pronounced and I can make out the arms a little better with your prints.

I'm going to keep playing with it.

Thanks again for the reference.

Your extruded lines line up better than mine do. I get some random lines that are laid slightly off of where they should be. Need to figure how how to dial that in.

"…laid slightly of…"
I wonder if the tightness of the "X" and "Y" belts have something to do with it?

Your "circles" seem to indicate differences between the two belts.

hmm, maybe. They do seem to have a little slack. I'll try tightening them up.

a good bit of slack actually on my X axis.

Plus I'm using the ABP which has some known issues with sporadic movements. That could be an issue too.

Thanks for the advise.

Here is my little "red" man. They come from Mars, don't they? :)

Still look like a mummy at this scale.
