Welcome to the SeeMeCNC Community

I even run my build plate at 100 deg C. Make sure to keep any breezes away from the build space also, I put a temporary screen around my printer when I'm printing anything larger than about 2x2 just to keep things from cooling too fast (that's what causes the curling)...

Is your trouble all on the first layer? If so, try making your Z distance shorter by 0.1 or 0.2mm in the EEPROM settings... I had a problem where it would extrude into open air just fine, but, the added pressure of the narrow gap on the first layer would put enough backpressure to cause skipped step...

I just put in 0.90c, is there a big reason to upgrade again? What's new between the versions...

Tony

Great response, thanks... I tried re-routing my USB cable away from anything else and trying a different one. I haven't tried the same program that was giving me trouble before, but I have been printing test parts for a couple of hours with no sign of trouble... As for the hot end... I'm about ready...

So, what retraction settings do you use anyway? Since you brought it up...

Are you going to do anything to heat the space above ambient or is this just something to keep the drafts away in your case?

Very very nice work by the way. You might have mentioned it, but, what material did you print the pieces out of?

Tony

I've tried looking at the path on the screen and watching something else.. It doesn't seem to make a huge difference... It says I'm running the latest version of Repetier V0.90c I'll try screwing the parts together tighter, but, I'm worried that won't stop the plastic getting around the PTFE liner a...

I'm having 2 problems. They are not related, but it's frustrating... looking for any insight into either one of them... I tried upgrading to the new nozzle in my hot end and my PLA keeps oozing out around the nozzle. I've tried adjusting the length of the 2mm PTFE insert and I'm not sure I'm doing t...

Thanks for the link. I still had to whittle down the 2mm Teflon part to let it slide in... Just about to print my first part with the new no22le now...

So, I finally got my new hot end nozzle in the mail today (thank you guys) and I'm trying to figure out how to install it. I'm wondering if I need to get a different insert or modify the one I have. The new nozzle only measures 3.8mm and the insert it 4.0mm even. So, the small tube doesn't fit down ...

I use Cura and I've set the build area to be very small (10mm x 10mm or something). That way the parts are only slightly off center. It works just fine (for my purposes)...

It's a kit, they tell you that you need soldering skills,it takes people that already built a 3d printer 12 hours top to make, You I am assuming are new so it is clear that you would need more time. I'd love to see someone build one of these in 12 hours... I didn't time my build, but, it was probab...

Yes, it's the firmware referenced above and the 0.83 version of Repetier http://www.repetier.com/download/ I didn't do anything special. I did have it working with the Marlin firmware already, but, it stopped working when I first switched over to the Repetier firmware until the latest changes... The...

For what it's worth I upgraded to the new version of Repetier (with the round build space) and the LCD enabled version of the firmware and all is well... I haven't had much time to print much, but, I did do a 3 hour print overnight last night with no issues...

FYI

Tony

The longest print I've made so far was about 9 hours with the Repetier firmware... I've never seen this error... interesting... maybe something with your computer? Do you have the LCD screen and SD card? Maybe try printing from the SD card and see if you get the same problem...

Tony

I use Cura for just about everthing now... Kisslicer is also very good, I gave up on Slicer long ago...

I'm getting ready for the 2 print head option... I've got a bunch of parts that need support lined up to print... I figure I'll start by printing PLA maybe just as a cheaper option to work out the bugs and then get some PVA... Anyone else try that yet? Have you thought about how the 2 heads go with ...

I am Soooooo much happier with this firmware... the motion is smoother and it lays out plastic more evenly... big improvement (IMHO)... I do have 2 comments: I get inconsistency on how it "homes"... I had to slow it WAY down from the setting that it was at when I downloaded... also, I don'...

This was one of my test prints with KisSlicer and the Repetier firmware... really happy with the results...

Here is what it is:

Ok, I'm used to reflashing the firmware to change those kinds of settings... so, this is a welcome change, much easier to deal with... I lowered the Max and min and I'm getting about a 3 degree overshoot (about what I expected)... My prints are looking pretty good so far and the machine just sounds ...

I flashed back the firmware that I was running and I'm seeing about the same difference between the thermistor and the TC that I'm using. So, for what it's worth it seems to be working just the same. So, that's good at least in the respect that my "calibration" for print temp doesn't need ...

Ok, I haven't printed anything yet but OMG is the motion smoother... I've been wondering why my machine used to shreak (about the best way to describe it).... Now it makes much smoother and more muted tones... it's sooooo much nicer to watch it move around... I'm tuning the PIDs on the temp control ...

Thanks...

I've been using Cura for everything... I haven't played with KisSlicer... Still using Repetier for control of the device and just importing g-code I assume?

Tony

Looks great, how much retraction are you using and what do you slice with?

Tony

Cool, glad it worked out for you. I'm very happy with how things are working out since I added my offset... I'm able to get the first layer on pretty large objects to stick much easier now...
