Welcome to the SeeMeCNC Community

What speeds are you finding work best with the .35 nozzle? I was planning on installing mine this weekend and would love to try out some PLA to compare it with my .5 stock nozzle. Printed on another machine with a .4 nozzle and got really nice results so I can't wait to see what this will do for me!

Installed the "new" threaded thermistor from Ebay, modified the configuration.h file and updated the firmware. Still having the same issue during the Autotune test... This is a video of the LCD as the autotune test heats up the hot end... at around 140C everything goes crazy. Prior to this, I had a ...

Looks like a board problem with Rambo, wonder if clearing the eeprom would help. Thanks for the suggestion. I did clear the board and reloaded it again. Gave me the same results. Started taking the head apart... again and noticed one heating resistor lead was close to the head so I bent it back and ...

Really too bad that there isn't a better way to protect those things being that they are so delicate... Checked my configuration.h file and it was already set for #define EXT0_TEMPSENSOR_TYPE 97 Just ran the autotune again, got to about 180C then jumped to a -18C then back up to 80C then started ...

I did do the tape method and got several very nice prints. When I powered up today I couldn't get the hot end to heat up to 225C without it failing and then giving me a -C reading. Checked the wires and nothing was wrong. I bought one of the other thermistors figuring I'd get a second extruder to ...

Been ...

That is really cool! It had to take a lot of time to do but worth it in the end. Great job! Thanks! Been trying to see what works best on my machine using ABS, so far these settings are doing well... I haven't played with the layer thickness yet and am still experimenting with the supports and ...

Been playing with settings on my V2 and various ways of slicing the models up for printing. Using 3dstudio max I cut this skull just above the nasal cavity and was able to print it with no supports by inverting the bottom half.

Finished up with these accessories for a buddy of mine... ABS at 230C with honeycomb infill and cut in halves then will be glued together.

Printing a little toy figure in ABS for a friend at about 4" tall with supports for the first time. Honeycombed the infill and added supports with rafting to keep them stuck to the base.

Good to know before I drive myself crazy trying to fix it! Thanks.

Just an update on the thermistor problem... got my new one from SeeMeCNC and installed it with the kapton tape method. Everything going smoothly and first prints look very promising. Other than the PID autotune with the new PEEK fan installed, PID autotune for the bed, the proper Z-height and ...

The end of my first day printing saw 2 prints of the PEEK fan, 1 print of the Layer fan and a replacement gear I modeled in 3D Studio Max for my weedeater. Still have some fine tuning to do, but the ABS I bought from Inventables.com has been doing great right out of the box. I upped the temp for the ...

I filed mine a little before inserting the fan, but had the same problem with it being too small... Everything else on mine fit fine though.

...And here is the video timelapse of the 1st build!

New thermistor received, installed and calibrated! Here are some shots of my 1st print of the PEEK fan shroud using the setup in the documentation with ABS. Timelapse video to follow! (Its still uploading to Youtube) The final print images are as is, no clean up has been done post printing, only ...

if your going to use that style, i sugest insted of the tubing, just spread the leads, and use kapton tape 4.PNG Good idea. I was just following the documentation since it was my first printer build. Figured it would be easy since I've assembled over 12 RC Helicopters... Problem is my big hands ...

Me likey! Makes sense being that those things are so fragile!

Almost at wits end with this... I've wiped the RAMBo at least 10 times now and reloaded, recalibrated etc only to get the dreaded def/0 popping up just before I print. I've checked all my wires just as many times and even with a meter. I've reseated the thermistor in the head and got really good ...

So yesterday I decided to reseat the thermistor since nothing else seems to have been a long term fix... Today everything seems to be going well. I ran through all the setup steps, ran the PID auto tune, calibrated the Z-height and even got the filament feeding. So now I'm slicing up the PEEK fan ...

Spoke too soon... it seems that the Mac Version of Repetier doesn't like to communicate well with my printer... going to have to try it out on a PC to see if it works. I got past the bed and hot end auto tune and then to the extruder section and now Repetier won't heat the hot end or bed by putting ...

Cheers! I am in the middle of the setup tests and calibration right now. With any luck, my ABS will be on my doorstep today and fan shrouds will be printing by this afternoon!

Just finished completely re-wiring the hot end itself with a new quick release. Either my moving it around or excessively taping it this time worked! Got a good temp reading and the PID auto tune is working on t0 like it should. Thanks for all the suggestions and your help!

no i forgot to tell you to change something in your pins.h scroll down to board type = 301 change the values to match this #define HEATER_BED_PIN 3 #define TEMP_BED_PIN 2 #define HEATER_0_PIN 9 #define TEMP_0_PIN 0 #define HEATER_1_PIN 3 #define TEMP_1_PIN 2 #define HEATER_2_PIN 7 #define TEMP_2 ...
