If the frame is square it works fine. if your frame isn't, all bets are off.
Well, isn't the question about how to determine squareness. The only way to do that, other than a lab instrument to measure 90°, is to measure the diagonals. But on printer hardware, measuring two diagonals accurately seems to me to be pretty difficult. The easiest thing one can d

The way you know if the belt tensions are correct relative to one another is that the X axis is square with the Y axis. The absolute tension is another matter- it should be tight but not too tight. In my printer the belt tension is adjusted by sliding the motor mounts back so I get a direct feel for how hard I am pulling on them. If your belt tension adjustment uses a scr

If you have a heated bed, that 5A supply will not be enough. Heated beds draw 9+ amps, I have one that draws 12Amps. If you are powering the hot end at the same time that could add another 3 Amps. And, you want margin (more capacity than you need) to handle surge currents. Power (Watts) = Volts X Amps. In general, you want a 50% margin. So, if worse case here we have 15 Amps at 12V that is

I noticed that de42 had suggested dropping your z acceleration speed and am wondering if you had tried that and by how much? I had a bit of an issue with the Tronxy x5sa pro when I increased the overall acceleration speed (M8008) from 100 to 700 and the Jerk (M8007) from 20 to 10 and that resulted in a total stop when the head went from front left to rear right and the z started.

The dual Prometheus system can be installed as a single filament system to begin with. I wouldn't hesitate to recommend the Prometheus system as mine has run flawlessly for four or five years.
The OP said he was cost sensitive. Prometheus is not a cost sensitive purchase. I have been using a Cyclops for years flawlessly too, for quite a bit less. However, you need to load both f

Nope, not enough capacity. And quite frankly, it isn't a very good board - My serial port has stopped working on my A8 and I am down to printing with the SD card only.

You could also raise the steps/mm of the extruder motor
Good point. He is trying to get the same flow as movement as well, which will require some other knobs - your dodge would also work on his X/Y steps/mm as well. There are a lot of knobs and it sounds like an interesting project to experiment with.

I do not have an explanation how fixing a play leading to the carriage rotation can fix the problem with periodically changing wall thickness you presented in the first picture. Carriage rotation play leads to significant errors in the XY-direction. But the problem is that this play should lead to an error which has period of one layer. While the error in your picture has o

Try looking at the problem a different way, you have more than one knob you can adjust.
Set your nozzle size to something like your actual one.
Then play with print speeds, flow rate, layer width and extrusion multiple. All of these can be tweaked separately on CURA, on S3D, you only get speeds, layer width and extrusion multiple. Not sure about other slicers.

If you have ABP and click the "download all" button of a thing the download never starts if you using chrome.
If you download just one file, this is still allowed.
Tied while not logged in and while logged in, it made no difference.

That's one of the reasons that we normally put filenames and other string parameters in double quotes. But it's optional, for backwards compatibility.
A space character after M32 would also work.
I never thought of it until I got bit. Not a big deal, but yeah, I will be fixing that script.

I have been reading that you need to have a Visual Studio IDE to compile for the 32 bit boards.
Most of what I read is that it is a bear to get that to work. But, people don't usually post that everything is great and that they have no trouble.
Does Marlin 2.xx now support configuring with just M commands like Reprap or do you still have to re-compile even to set a delta Z height?

My feeling is that the patent system is so broken that it isn't even worth while. The burden of defense lies solely on the patent holder to defend it. In which case, unless a mere mortal finds a wealthy patron, the "Evilcorps" out there will steal it with impunity and even the actual patent holder can't use it.

I am using Exoslides for a CoreXY home-grown project.
Each "glider" uses three Exoslides.
The Exoslide creator says that you need to mount the "load" on the center slide of a three-sided slide, other wise use four.
I violate that rule on two out of three of the slides - Maybe, what is considered to be the load? The slide with the belt pulleys or the side that is attached to the extrusion on w

I decided to create a CoreXY using a Duet Maestro and a bunch of spare parts that I had lying around. I have gotten Delta's down to a science, and while they are easy to build, and space stingy, they are hard to tune when you want a large build plate. I didn't want a big bed-slinger, so CoreXY.
Unlike the Cartesian printers, which are hard to build, but easy to tune, I feel that the CoreXY is b

I have had two of them fail in the last few years. Usually contrast permanently dims, one just stopped displaying anything.
In the end, I just replaced them. They are cheap, which is probably why they often don't last very long.

I finally figured it out. It was a purely mechanical issue, and really subtle, but obvious once I stumbled upon the reason.
I use Exoslide hardware for my motion control slides. I had to come up with totally custom pieces for my CoreXY, but hey, who hates a challenge?
Anyway. This was a scratch built, parts from the bin, whatever was lying around and crafting up the rest. I had gotten the Exo

Maybe the range of adjustment for the belt tensioners is too small. It should be impossible for the motors to apply enough force to get the drive pulley to skip on the belt teeth.

MKSA is absolutely correct. One stepper, a couple of pulleys and a belt loop. The lead screws on the printer work well enough with a single stepper and you won't lose any Z height. My scratch built CoreXY is done this way. With some careful measurement, you can get the loop exactly the length you need.
