Since i switched to glass I have been wiping it down with isopropyl alcohol and balsamic vinegar between prints. I have not had a single problem since i started doing it this way.by Thelandofthedave - General Mendel Topics
Yes true. I meant to say look like small diodes. My bad.by Thelandofthedave - General Mendel Topics
There should be two temp sensors. One for the extruder and one for the bed. Both are small diodes that need to be attached to the extruder and bed. If the extruder sensor is not connected you will get the error you are getting. Im terrible at explaining how to attach things. Google or search youtube for how to attach thermistor to extruder. The DIYTS instructions that came with my kit were sby Thelandofthedave - General Mendel Topics
Make sure your temp sensor is connected correctly. Then you will want to follow a calibration guide. This one is a good one. I just recently got my DIYTS i3 setup and running too.by Thelandofthedave - General Mendel Topics
I picked up a new MEGA and I am printing again.by Thelandofthedave - RAMPS Electronics
arduino clone was the culprit. authentic mega and im back to printing.by Thelandofthedave - General Mendel Topics
QuoteBensonthe3rd I tried that to no avail with mine, I also discovered that somewhere in the works the extruder drivers no longer power an axis motor if i swap them, so i tested the voltage and i'm not getting power to the extruder pins. Might reflow or replace the MEGA with a legit arduino instead of the sainsmart version i have now I too had a sainsmart arduino replica... Just stopped and picby Thelandofthedave - RAMPS Electronics
have you calibrated it?by Thelandofthedave - General Mendel Topics
Quoteparasut OK, I have a solution to my problem, let me share. Actually it is not a solution but a workaround. First I dissasembled everything and re-flowed all solders on RAMPS and Arduino pins -not components but pins-. Then I moved extruder0 cables and stepstick to extruder1, did not work. Then I tried changing extruder0 to X-axis pins, re-cabled and modified Pins.H accordingly, extruderby Thelandofthedave - RAMPS Electronics
Just read in another part of this forum that swapping x axis and ex0 in pins.h worked for a person experiencing my exact problem. Will attempt tommorow.by Thelandofthedave - General Mendel Topics
Ok out of the blue my extruder stopped extruding. This is what I have done so far. Swapped stepper driver board with a known good board. This did not work. Plugged extruder motor into x axis driver and find the motor works fine. Plugged known good motor into extruder driver on ramps board and no go. Hmmmm I have a spare ramps board. Swap the spare ramps board and no changes. Change E0 to E1by Thelandofthedave - General Mendel Topics
My heated bed from diy tech shop is 8.25" square.by Thelandofthedave - General Mendel Topics
Got the glass. Im finding that the advice to use alcohol and then vinegar seems to work just great. My prints so far are superior to anything i was getting on blue tape. I am finding that my first layer seems a bit too thick but i do not think that is related to the bed. I am going to play around and try to solve that and if not i will start a new thread. Thanks to all that gave me some inpuby Thelandofthedave - General Mendel Topics
Getting the glass tomorrow. Actually i just picked it up but i have some other stuff to take care of tonight. I'll start with bare glass heated to 60c and see what that gets me. Then i will start using suggestions you all have made.by Thelandofthedave - General Mendel Topics
Picked up a new power supply. Printing fine now with none of the above problems. I am having problems with my first few layers being a bit funny. but im getting my glass tomorrow and will see if that takes care of that issue.by Thelandofthedave - General Mendel Topics
That is the voltage regulator on the arduino. Something in your setup is probably shorted to ground. Make sure your stepper drivers are not installed backward. Can you uoad a photo of your ramps on the mega?by Thelandofthedave - General Mendel Topics
I'll be picking up glass on Monday. Blue tape has been hit or miss with adhesion issues. I still have the problem I shared in another thread with the motors shifting though.by Thelandofthedave - General Mendel Topics
Using the 10amp supply I managed to get one print. Not problem free but it finished. After the first layer I had a dramatic shift. Then it finished with no major problems after that. Was hoping to solve this before leaving town for the long weekend.by Thelandofthedave - General Mendel Topics
Here is what i have done tonight. No luck.... But. I did find my ATX psu is not up to the task. Although it states 12V at 25A. Monitoring the input voltage while printing i see that when the extruder heats up that i drop to 11.48V. When the heater is not on i sit at about 11.43V. Tried another PSU (not an atx) that is rated at 12V at 10A. Monitoring the input voltage while printing it dropsby Thelandofthedave - General Mendel Topics
checked my stepper drivers and they are still set where i set them last week. Belt is adjusted. printint direct to blue tape with so no heated bed to draw too much current from my psu.by Thelandofthedave - General Mendel Topics
That didnt fix it...... Also got a Big shift in the X direction this time too.by Thelandofthedave - General Mendel Topics
think i found it. my y axis belt was super loose. Printing a somewhat large piece now so i will see if its fixed.by Thelandofthedave - General Mendel Topics
So i have been printing trouble free for a few days. I have made no changes since switching to blue tape from Kapton. All of a sudden tonight I am having a new problem. This seems to be mainly in the Y axis but at one point it was the X axis. It will be printing along just fine and then i hear a loud jerking noise(or a grind perhaps) and there is a shift in the print. The last print i did waby Thelandofthedave - General Mendel Topics
I bought some glass today but will not be able to pick it up until after the long weekend next week, as i will be away. But i picked up some blue tape and placed it direct on my bed. That did the trick. Once the glass is in my hands i will experiment with all the various methods people have shared with me and see what works good for me. one thing i am seeing right now is my first attempt witby Thelandofthedave - General Mendel Topics
Quotejbernardis I never use Kapton with PLA only with ABS. For PLA, I use a wiped-on layer of diluted white glue such as elmers. I dilute it approximately 1 part glue to 4 parts water and it works well. What surface are you putting this on?by Thelandofthedave - General Mendel Topics
While I'm out I'm going to stop and pick up some glass. Hopefully tonight I'll be printing and sticking.by Thelandofthedave - General Mendel Topics
Im finding that my prints dont stick well when printing PLA to Kapton. I am printing 3mm PLA through a .5 nozzle. I have the bed heated to 70C and the hot end to 185. I am finding on small items it is fine. But on larger or denser items after about 30 minutes of printing the entire item will break free from the bed. From googling about on this topic im starting to think that printing to glby Thelandofthedave - General Mendel Topics
Grabbed one of my spare psu's and all is well now. Super stoked. Some tweaking to do with the calibration but happy to say things are working now as expected. I cant thank any of you enough that took the time to offer assistance.by Thelandofthedave - General Mendel Topics
When the bed and hot end are heating it drops to about 11.2 volts.by Thelandofthedave - General Mendel Topics
Good point about the amperage being combined +12 and -12. I will look into that tonight when i get home. Will check the voltage while heating also.by Thelandofthedave - General Mendel Topics
