[problem with cura]

I downloaded and installed Cura on my pc.

I uploaded firmware - seemed to be ok

I ran the installation pages of Cura

BUT the heating element did not function, so I could not test the extrusion length or move forward

Checking, the heating element works with ReplicatorG24

Why does it not work with Cura?

Thanks, EM

no, I did not download Marlin

I just copied it from

https://github.com/ErikZalm/Marlin

 

but how do I install it 1) on my pc? 2) on my iMac?

Is Marlin the replacement of SkeinForge? - see how far back I am?

Thanks, EM

[uneven printing]

I installed SF44 (2011-10-08) but the printing is miserable - no flow with the go - so I have the flow rate(128) at 4x the feed rate (16) and it is still miserable, no where near the glorious speeds I read in exciting, enthusiastic blogs

wazzitdoin?

Thanks - I'll do it

are there pitfalls to avoid?

are there cook=book recipes and acceptable ranges of parameters? I find so, so, so many variables and it is hard to know which are important, and which values to use.

[uneven printing]

I am using Ultimaker v1.0 5D firmware, with Skeinforge 35. The print rate is 16mm/s and the flow rate is 10mm/s, the temperature is 210C

[uneven printing]

The PLA thread tends to form little balls on the tip as the thread is being deposited - they make the surface lumpy and unattractive

feed, flow, and temperature seem to be the major variable

any suggestions?

thanks,

EM

-even worse, the flow stops 3 hrs into a 7hr printing job - it seems a plug forms at about the brass tube position and the PLA stops feeding

I am stopped by this most of the time

I need help - any suggestions???

thanks also,

EM

[Extruder issues]

Question: the PLA thread keeps balling up on the tip of the nozzle and not being deposited cleanly on the growing piece;

I imagine three variable are relevant: feed rate, flow rate, and temperature.

Anyone have any experience solving this problem? how about cleaning and care of the brass nozzle any suggestions?

Secondly, I bought and installed ball bearing races for the PLA spool to minimize friction and let the bolt work on feeding the PLA tubing.

[conservative print parameters]

I have a relatively new (2-month-old) Ultimaker.

I have conservatively tried to work with Skeinforge 35, but the number of parameters in PLA-Ultimaker-failsave v1 is overwhelming

help files such as

http://wiki.makerbot.com/configuring-skeinforge

are minimally helpful, partially because it is not a good fit and partially because it is sketchy.

can someone point me to a consistent set of parameters? I'm willing to try newer Skeinforge files, but I need to be sure that I have all the files, so as not to be left guessing.

many thanks!

[systems choice]

Daid,

How do I get the new versions you suggested?

My current choices are Skeinforge 31,35,40, and standard

[systems choice]

I have a new Ultimaker printer and am just learning how to use it

I find that only Skeinforge (35) with PLA Ultimaker failsafe v1. feeds PLA after the initial setup

and - without PLA feed, nothing gets drawn

any suggestions?

thanks, EM
