Re: Prints are too tall

Thanks Eagle! I usually take pretty good notes about changes, but I get a brainstorm and start fiddling and forget to write it down. I really wish I knew exactly what fixed it so I could maybe contribute a bit to others that have issue. The forum has been a big help to me in figuring things out and ...

Re: Prints are too tall

I went through the linked threads and saw nothing there that I have not already tried or checked. All my settings in EEPROM and software are correct (20 tooth and steps). The only thing off was the print area. I took a few days away from printing and decided last night to just set everything to defa...

Re: Prints are too tall

Adjusting rod length is the way to go I guess. I'm getting pretty close the 25mm target. Another adjustment or two and I think it will be darn near perfect. *edit After doing some reading it looks like the same results can be had by adjusting the Printable Radius. Mine is set to 138 (not sure where ...

Re: Prints are too tall

I was having the same issue with the steps. Changing the steps fixed the height, but now the X, and Y are too small. I used the calibration cube that was in mattercontrol, it should be 20x20x10mm. The Height is 10.08 , that is great, but now the X and Y are 18.22, and 18.26. The arms length is 269,...

Height 25.01, 25.11

That's awesome! Wish I could find out where my settings are off. Has to be maybe bed size or printable size? What are yours? Maybe I can compare.

Should be 269mm unless you have some sort of DIY arms.


Yep it is set to 269mm. I have attached my EPROM file if that helps.

Re: Prints are too tall

Setting the Steps to 80 and resetting Z height and changing firmware to match the new number results in a new cube about 23.75mm square at the base. It's still printing, but the height will probably be too high as the rest of my runs. Maybe bad slicer settings and firmware settings? *print finished ...

Re: Prints are too tall

That makes sense for your machine having an 80 nominal. 92.650 steps/mm / 80 steps/mm = 1.158. 29 mm / 25 mm = 1.16. 16% too many steps, 16% too-tall parts. Not looking like a coincidence. Solid math there. So I set the Steps to 80 and tried to run the cube print again. The print starts about 3 inc...

Re: Prints are too tall

If the height is incorrect, you have a bad setting in the firmware, most likely Steps per mm for X/Y/Z. That setting needs to be calculated from the pulley tooth count and the fact you are using GT2 belts. The correct setting for an Early V1 Max is 53.333333 steps per mm The correct setting for Lat...

Re: Prints are too tall

They seem consistent, but not accurate. My 25mmx25mm hollow cube is coming out about 26.4mm wide on all sides, but almost 29mm height.

*edit
Here is the cube file if that matters

If you move the head by typing G1 Z0.2 F3000 How far above the bed does it look to be, if it's correctly calibrated it should be 0.2mm If that is correct, look at the first few lines of the sliced object, and see what it is setting the Z height to, if it's much larger than you expect, you have a ba...

Re: Calibration Issue

I would think that just setting the Z height via the LCD should work fine. You should not have to do a complete calibration. Eagle, I guess my question is how does the LCD Z height calibration effect the 4 script calibration? Something isn't working for me since the 4 script calibration looks fine,...

Re: Hotend stops at 192c

ok, that isn't horrible. So I suspect your wiring and/or mounting of the thermistor. It seems the thermistor itself is in the ballpark. Well this was the bare thermistor in water and the wiring is completely new for the second time. I think wiring is fine now that I know what NOT to do when measuri...

Might give that a try. I did the water test and there is a 5 degree variance in temp from the thermistor and my probe.
