Re: Folger Tech 2020 i3 Printer Kit (Official Thread) - 9 years ago
Those looks like portion of the plastic lines laid out didn't stick on the build plate. Those are aren't due to stepper skips. This happened to me when i tried to apply glue stick while the build platform is still hot then immediately printing after that. They seemed like bubbles came out of the first layer. The only thing i can think of to cause this is unbalanced heating. You can still blastby wderoxas - Prusa i3 and variants

I'm going to try a different slicer(Cura, using Slic3r now), because I've only had one heart gears print off correctly, and four print with shifts. Try to use the z lift feature. Lifting it 0.2 or 0.15 mm on every retraction only marginally adds to the printing time. Its better than starting thby wderoxas - Prusa i3 and variants
Re: huge problem. I've got smoke. - 9 years ago
There are two sources of 5V logic supply on the arduino and ramps combo. 1st is usb, and the other is the 5V voltage regulator which you have described as "fried". This 5V powers all the logic supplies on the ramps - LCD, stepper driver, endstops.. For the 5V voltage regulator to work, it needs a 12V input which can also come from two sources: 1) From your psu via D1 on ramps; and 2) From the 1by wderoxas - Prusa i3 and variants
Re: X-Axis not homing - 9 years ago
There will be two cases of possible defect on that problematic cable. 1) wrong connection/orientation on the cable - you can check the wire colors on both ends and use the working ones as the reference.Shaking of the motor highly indicates this is the case. 2) one or two cables have loose/no connections - check each wires connectivity end to end. For the axes moving on opposite direction, you cby wderoxas - Prusa i3 and variants

Re: Folger Tech 2020 i3 Printer Kit (Official Thread) - 9 years ago
It functions as endstop only during a a homing (G28) or auto bed level (G29) . If you drive the head further down manually, it could crash into the bed. Reason is, the servo only gets activated during a G28 or G29. Not sure if case is the same for those with inductive or capacitive sensors.by wderoxas - Prusa i3 and variants
Re: Folger Tech 2020 i3 Printer Kit (Official Thread) - 9 years ago
My endstop was at the head cause i was using Auto Bed Levelling. There's a servo just left of the fan to place that endstop into position during Z homing or auto levelling routine.by wderoxas - Prusa i3 and variants
Re: Folger Tech 2020 i3 Printer Kit (Official Thread) - 9 years ago
This came about as it is now cause i had always wanted to put those diagonal braces between the Z post and the back of the bed. So i had to get rid of the supply from the side. The best place i could think of is below the bed.. So i had to raise the base, similar to the mendelmax model. Those corner brackets were taken from the mendelmax's. That's basically the motivation for the change on thatby wderoxas - Prusa i3 and variants

Re: Changing Homing behaviour - 9 years ago
Oh, i see your problem now. The second probing square you listed really wouldn't work no matter what you do with it. Since your 0,0 location had been configured to the upper right corner of the bed (when looking from the front), you should also change your orientation on defining the probing square. The best way for you to picture this is, look from the back of the printer then visualize the wroby wderoxas - Prusa i3 and variants

Re: Changing Homing behaviour - 9 years ago
Yes, thats the "conventional" back. Its up to you entirely if you want to move the conventional 0,0 point at the front left of the bed. All it takes on the firmware is, enabling the pullups for the xmax and ymax, changing the home for x and y to max, and moving your x and y endstop connector to the x and y max pins at ramps. You should then change your printer homing locations too should you do tby wderoxas - Prusa i3 and variants

And another thing, im not sure if your z probe/sensor needs it, but you might want to check if it needs the #define ENDSTOPPULLUP_ZMINby wderoxas - Prusa i3 and variants
Re: Changing Homing behaviour - 9 years ago
I think this is where all the confusion stems from. The point you labeled as home should fall on the left-front of the bed, in reference to the cartesian coordinate system. In your case, you had it at the opposite side. This is why, when you mentioned that your y endstop is at the front and x endstop at the right, i told you to home at xmax and ymax. In your case, since you all had your home sby wderoxas - Prusa i3 and variants

Quote55rebel hmmm?.... now that I'm looking at the defined rectangle in Marlin, they seem to be reversed. My X axis end stop is on the right side of printer, and Y stop on front. .....I'll get back. P.S. Well, reversing X & Y probe points, to where they would seem more friendly to my build, throws up an error when compiling: C:\Users\Mark\AppData\Local\Temp\build1479576133429720467.tmp\Coby wderoxas - Prusa i3 and variants

Quotejimmyclarke Hi Thanks for your response, after reading what feels like every internet page on auto leveling I finally found where I was going wrong!

Re: thermistor location? power cable connections? - 9 years ago
Practically speaking, any thermal interface between the plate and the heater is unnecessary. While not flat, the heater do have a bit of flex. So if properly mated with the glass, you'll have an acceptable contact area between the two. Besides, there will be a point where you will need to remove the glass from the build plate.by wderoxas - Prusa i3 and variants

Quoteanimoose Here's a description of the X/Z rebuild: . Good going with your "moosebot". The kit's ability to go for a 50 micron layer height was an unexpected effect of using the leadscrew. In your case, using a 4 start lead screw (8 mm per turn) further reduced the available steps/mm but still, theoretically, you could go until 2.5 micron layer height with that.
