Welcome to the SeeMeCNC Community

Does anyone know if there is an avilable metal upgrade for the carriages, similar to the tricklaser ones? TrickLaser appears to be out of buisness.

Just checking in to see if you ever had any luck with your calibration issue?

I noticed a similar issue with the Octopi calibration plug-in. It seems to travel too fast. It seems to travel so quickly that it does not travel at a steady speed from point to point. I never noticed this issue when running any other gcode.

Just checking to see if you've made any progress on the outer perimeter sine wave calibration issue you have. I have the exact same issue, I see where the previous post made mention of spring tension contributing to it. I had the issue with super loose stock arms and springs and with the TrickLaser ...

Ok, I checked all my bed mounts and they all measured the same. I put them back on in random positions. I tried different rotations for the bed as well, same result. I now calibrate with no bed heat as well as print without bed heat and that has improved my first layer by quite a bit as you can see ...

I'll check all those things, but tomorrow I plan on re-calibrating cold bed and printing to a cold bed to see what differences that makes.

That is one of my troubleshooting steps, eventually, but in relation to deviation numbers, my cold deviation numbers always matched the warm deviation numbers. I need to correct myself in regards to my previous post. I prematurely stated my test print was perfect, that was wrong, after I pulled the ...

So yes Toddwagner, I agree, I stopped getting hung up on deviation results and started to just concentrate on test print results. Except, my test prints were failing miserably. I had bad test prints and no deviation lower than .17. Then I noticed something peculiar, any temp much above 50 deg C and ...

Printed the 50 mm test piece and came up with 49.5 to 49.55 mm dimensions. So I dont consider 7 factor calibration to be the solution.

If I use the least squares calibration and choose 7 factor calibration, I get a .03 deviation with a new DR length of 307.81mm, which is up from the 300.15mm of the original length. From what I have read though, this is not the solution since it will affect the scaling of the print object. Have you ...

Well I'm afraid there has been no change for me. After installing the new arms and effector plate, I cleared the EEPROM and and reflashed. I then ran G29 multiple times followed up by the Octoprint delata calibration plug in. It can only get me to .17 deviation. When running the gcode for the same ...

Toddwagner Thank you very much for taking the time to respond with pictures and settings. I will compare tonight after work (I should be working anyway... :D ). As far as fan shoruds, I really like these http://repables.com/r/832/ . They fit right on the little tabs at the 3 locations on the bottom ...

Good News Todd! I also received my carbon fiber delta rods and aluminum effector plate. I installed last night but did not have much time to run calibrations, but my initial pass through delta calibration still showed high spots between the towers as reported back by the z probe. I ended up only ...

For me, big issue, because the bottom layer is the top to some of my prints, like a phone case for instance.

A quick update: So I have been getting pretty good prints since I modified the way I calibrated the machine. I calibrate with the machine at printing temperatures and the probe points moved in from the outer perimeters. With the calibration wizard I get a .02 deviation. I put on my new bed insulator ...

I came out at around 49.9 +/-. I plan on re-calibrating with a shorter DR length to get it even closer. The firmware comes default with a 291.06mm setting but I read a post where geneB states the length is 290.8. Calculating with 626Pilot math, 49.9/50 = .998 x 291.06 = 290.477. I will try that once ...

Sounds like maybe you need to tweak your z max height. I do it by manually adjusting that setting in the eeprom as opposed to using the lcd screen to adjust it. It's the same difference from what I can see. That is if the .3mm gap is consistent across the entire print. Increasing z max height will ...

Yes, I'm speaking of the escher 3D program. As far as the X/Y coordinates, in the firmware are the programmed points for the probing locations when using the G29 command. You can change the points to custom locations for better probing. I forget the exact label for them but its something like X1 Y1 ...

OK, too scared to call this solved just yet.... I had my printer almost disassembled looking for any sign or clue of an issue that could be causing poor calibration of the outer perimeter. Nothing I looked at or adjusted made the problem go away. So I gave up and decided to put everything back ...

Interesting, but I think I found the solution to my problem, at least for the x tower issue. after trying everything, I noticed the hotend whip was leaning against the delta rods for the x tower. I adjusted them and re-routed the bowden tube away from inside the sleeve. That helped tremendously, my ...

OK, just make a file with the extension .gcode. Then just paste the code into it. Load that up in your software, right now for me that's MatterControl, then run the program and watch what offsets it prints out to the terminal.

Yes!, great idea I am very curious what your output is. I built my machine myself. G28 G1 Z10 G1 X0 Y0 ; G30 G4 S5 G1 X-15.53 Y-8.75 ; G30 G4 S5 G1 X-31.06 Y-17.5 ; G30 G4 S5 G1 X-46.59 Y-26.25 ; G30 G4 S5 G1 X-62.12 Y-35 ; G30 G4 S5 G1 X-77.65 Y-43.75 ; G30 G4 S5 G1 X-93.18 Y-52.5 ; G30 G4 S5 G1 X ...

ToddWagner, my failure after adjusting Steps/mm to achieve a low deviation and eliminate my outer perimeter sine wave (high between the towers) was that I did not print a full bed test piece. I just took it for granted that my first layer problems were gone when I achieved a low deviation with the 6 ...

Swapped belts from one tower to the next on all 3 and even fed the belts in from the opposite direction to ride on different teeth to eliminate some belt issue. No luck, offsets were still as follows... .01,.01,0,-.01,.01,.02,.01,-.02,.16,.12,.09,.04,.03,.02,.01. Still a big jump in z offset on the ...

Well, checked belt tension and adjusted, checked pulley alignment and adjusted, tried higher current settings in firmware, ...no luck. I even swapped out the x tower servo since I had a spare from another project....no luck. Every time the z offset is fairly close from bed center to X tower ,then ...
