Abandoned 3D trying to get working (Page 1 of 3)

Aah Thank you.

M119 gives me: x_min:H y_min:H z_min:H.  Pressing an end stop manually it works in the "-" zone. It also helped me realize I had my Z and X end stops wiring was mixed up. I went in to Arduino and changed the config to "true" for all three end stops and I am now able to go both ways.  I feel this will be  a long road ahead of me.

Thank you Carl.

I hadn't even thought about looking for old printers at second-hand shops!

Tin is right:  you've come to the right place for help.

You can also find them on Craigslist in your area as well if you have that service in your area. Also go garage sale hopping on weekends.

Well, looks like important parts are all in good shape, $10 is a great deal. Once you get it up and running, you can download and 3D print the broken frame parts to replace your temporary solution.

You can use power supply from old PC if the heating element and heated bed use 12V power supply. Some large format scanners or inkjet printer at fleamarkets also use 12V 10A(or bigger) power supply.

It is also a good idea to clean and lubricate the rod before test to avoid damage.

Yizhou - I converted a PC power supply long ago. Burned it up long ago as well. If I remember I had to dismantle and add some ceramic resistor or something to allow it to come on. They probably have an easier way these days but I wasn't sure sure if any of my spare power supplies had the same AMP rating. For 24 bucks I ordered a power supply online. I needed to buy a spool of plastic anyway.

Frame was patched*. Now that the I am able to 'motor' in both directions I can continue to calibrate. Good idea, I will oil up the threaded rod and slide bars. My next hurdle is to get the heating (extruder and bed) working. I have not touched these yet.

*My one virtue is I worked in a steel fabricating shop (to pay for college) and have a slew of metal and woodworking tools (a semi-serious hobby). Actually that is why I collected stepper motors as I wanted to make a mini CNC machine. I just didn't have brains (literally and figuratively). The 3D printing community has opened up what I wanted to do 25 years ago. Very cool.

Yes it's a RAMPS 1.4!

Instead of messing around with old power supplies. I highly recommend a supernight psu. Most of us use these and they'll give you all the power you'll ever need on the printer. https://www.printitindustries.com/produ … wer-supply

Probably should of came here first but I had already bought a Zyltech 12 V 30A 360w PSU and spool of 1.75mm black ABS.

I think I have it calibrated. I did notice the bed stepper motor gets hot unlike all of the other motors. This may have to be replaced one day.

Tested the heating elements both work. Didn't use an outside thermometer to compare what the CPU was telling me. I guess soon I'll try the 20cm cube.

The previous owner was sooo darn close. Not sure why he stopped. Ah well...

The bed stepper could have too much current driving it. May need to adjust it.

I tried printing today. I am having a bit of trouble extruding. In Pronterface when I go to print. The temperature (at 230 for ABS) clicks down to about 200 in the side window then starts to print. I just get a little plastic hairball on the bed. I would assume that the extruder needs to stay at 230 degrees. Any help?

Sounds like your slicer is set at a lower temperature than your host is. Both need to be the same temp.

That is correct. Be sure to keep a log of your settings. I learned the hard way of not keeping one. I learned not to make to many changes at once.
