You sure that is not a problem with the drawing. Maybe not enough segments defined. It looks too consistent to be a mechanical problem.by rcazwillis - General Mendel Topics
Are you using PLA or ABS? I find the purple glue stick works very well with PLA.by rcazwillis - General Mendel Topics
Looks like your Z zero is too high. Should be paper thick high.by rcazwillis - General Mendel Topics
On my first menu there is an option "Print from SD." I am using Marlin.by rcazwillis - General Mendel Topics
I have wondered the same thing. My CNC mill is run through mach3. I thought it would be handy to have an SD ramps run the mill.by rcazwillis - RAMPS Electronics
Reflashed marlin, no change. Pulling my hair out.by rcazwillis - RAMPS Electronics
I have the same issue with the latest download. Shift_clk not defined and whole host of other errors when Ultra_LCD is defined.by rcazwillis - Firmware - mainstream and related support
Anyone have any idea what causes this? It immediately started doing these programmed moves this morning.by rcazwillis - RAMPS Electronics
Here is a video of what I am talking about. Could this be a firmware issue? Am I posting it in the wrong folder?by rcazwillis - RAMPS Electronics
Definitely fried the mosfet. Black and melted. Where do I get a replacement? What part?by rcazwillis - RAMPS Electronics
Seems like this is a heat issue. For some reason, the fan continues to get shut off. Help!by rcazwillis - RAMPS Electronics
Any idea why my Ramps 1.4 Prusa I3 would randomly, during a print, move to the home position on X, Y, or E when it is not in the G code. Last night, I was about 45 minutes into a print and the printer moved the X axis to the home positon and back to printing. Later, I witnessed it retracting filament to the point I thought it was going to unload. I have seen this behavior multiple times and haby rcazwillis - RAMPS Electronics
The hole needs to be smaller than 3mm. Look on the tap for a hole size or drill to use. It will probably list something like "no. 32" and you will have to cross reference this to a drill diameter. If it is not on the tap, look up a metric tap chart on the internet. I would have the holes cut smaller than needed and then drill the to size. You will be tapping very small threads and a good holby rcazwillis - General Mendel Topics
I verified the supply and it is correct; positive to the positive on the board. Last night I let the magic smoke out of something. While heating up, something started smoking. Before I could get it unplugged the smoke had stopped. Now the bed does not heat up, but everything else works fine. Did I smoke a mosfet? How do I verify? Where do I get a replacement?by rcazwillis - RAMPS Electronics
Last night the bed started to heat up. Now it does not shut off. Set temp to 60 and it heated to 90+. Never reached 100. Red LED is on. Choosing cool down on the lcd shuts down the extruder, but the bed remains hot. Any ideas? On the plus side, the ABS part I printed turned out very nice.by rcazwillis - RAMPS Electronics
No, the LED does not come on. The one for the hot end does when it is heating.by rcazwillis - RAMPS Electronics
I am trying to get my heated bed working with Ramps 1.4 & Marlin. Bed came from Sainsmart and is the 12/24v version hooked to D8. I have a big power supply set to 12v on both power in points. Thermistor is reading room temp connected to T1. LC display shows B020/060. So it is showing temp should be at 60. However, I get zero voltage out of D8. This is a new printer and the heated bed hby rcazwillis - RAMPS Electronics
You can certainly calibrate any axis through measurement. Actually, it is the most acurate method. I was having a similiar issue until I realized I was not updating my actual steps after each change. I would calculate the necessary steps, make the change, and remeasure results. In the calculation, I would use the original steps not the ones I had just changed in the firmware.by rcazwillis - General Mendel Topics
I have not, but it looks awesome. You are going to have two X axis running on the same rail. How do you plan to prevent colliding the heads into each other? Is your plan to make two pieces of the same part? I think most dual heads are for printing multiple colors on the same piece.by rcazwillis - General Mendel Topics
If Y & X are mechanically the same, the steps should be very close. If you have different size pulleys, then the steps would be different. I would start by slowing down your speeds. Instead of 500 mm/sec, use something like 25 mm/sec. This will insure your steppers are not locking up. Then start turning the speed up once calibrated.by rcazwillis - General Mendel Topics
Might be running the steppers too fast and they are locking up at times. I had the same issue until I realized the homing speed is mm/minute and the max speed is mm/sec. Big difference when you set them to the same number...by rcazwillis - General Mendel Topics
I can find no bump in the ones I have. I did manage to decipher the adjustment and have the motors running well. Ended up adjusting them to a point where they would lock up quietly. Seem to run smoothest at this point.by rcazwillis - RAMPS Electronics
Excellent! That answers my original question perfectly. Now to find the answers to all the other questions!by rcazwillis - RAMPS Electronics
I asked the question because I read advice on setting the driver by turning the pot until the motor does not twitch plus an eighth turn. Then other places I read turn to zero and increase 25%. This indicates there should be a zero stop point. I also see info to set the voltage, but can't find a clear direction on what to set it to or where to measure it. If you start researching it from a totaby rcazwillis - RAMPS Electronics
When adjusting the current, how many turns will the pot physically make? Is zero to max 360 deg? If turned past 360deg, does it go back to zero?by rcazwillis - RAMPS Electronics
