thank you. I had to run my steppers at 1.4A to get rid of some defects caused by the tight wheels. Now I have them adjusted properly thanks to your video.
Thanks! Mine were really tight too so started googling how these should rotate. I feared ruining the threads so instead screwed two bolts in partly and used screwdriver between them to rotate the housing. This gave a better control for the adjustment too. Best way to check that it's not too loose is wiggle one end up and down to feel when there's some play and then tighten it back just a bit.
I did same way using two bolts - leaving one grub screw in as well. then use screw driver to lever adjust - tighten grub screw, remove bolts fit other grub screw
I had almost worked this out myself, you confirmed which way to turn the wheel, many thanks. No way would my rail go on as supplied......unless you used a hammer !!!! Then I had to disassemble the whole hot end assembly (like you stated) to do the same with that carriage & wheels to get it on the rail, major PITA!! Anyone doing this, after taking the fan housing off, DO NOT try to force the base off the carriage once you have taken out the 2 small screws that hold the base and bracket system on. You have to then loosen off the 2 small screws in the stop end sensor to get the base to come off as these 2 screws also are threaded into the carriage/hot end base plate. The thread for these 2 screws is slightly oversize so the base moves slightly like it wants to come off. It's not immediately obvious they are threaded in as those screws are very small.
As an addendum to this, don't shove a pair of pliers in the holes use the spare bolts they give you to provide two pillars you can place a screw driver between and it turns way easier, far better leverage.
The video was made at like 3am in the morning and I was tired. As you can see by the date of the video, i was one first in the US to get this New printer and they didnt get any instructions the new rail system at all at the time. Even when I sent a email to customer support they said at the time sorry we have nothing. Lucky one of the customer support guys figured out that if the rail wheels are not perfect, problems can happen. He was the one that said to use a pair of needle nose pliers. I really do need to make a updated video of 16 months or is it 17 months of using the printer. As the Hotend is a E3D Hemera direct drive now, its in a temp controlled heated enclosure with electronics outside. I been moving more over to large resin printers, but this is still my favorite printer.
@@steamcastle2473 Well their manual still doesn't tell you how to adjust them and this is the only video I could find that said "just do this". My comment was on how to improve the adjusting experience, so thanks for the knowledge it was helpful.
@@TheShorterboy I still remember that night I was so mad at the printer. I thought I had defective belt motors as they were running so hot you couldn't touch them. I was told a few times by Tronxy support that the rail wheels do not need to be touched as they were set at the factory. But once one guy over there figure out what was happening and sent me a video on how to set the rail wheels. After setting the wheels correctly my printer was golden. It was like night and day.
Thanks a lot for the video. I got the same issue. All three rails were pretty tight. Hotend one was a bit pain. I was almost going to return the item. Looks like Tronxy got a great quality team.
I don't know if they fixed the hotend rail adjustment problem(the center rail). On mine you can only adjust the hotend rail wheels by removing the whole dam hotend and hotend mounting plate as it covers one of the rail wheels.
Correction... it does not tighten or loosen if you turn clockwise or anti-clockwise. You are just rotating a hole that is excentric in the piece that you are rotating. It is not a screw it is just a piece that rotates in place. It is looser / tighter depending on the orientation. One semicirle will be righer, the other will be looser. If you want to loosen it, try to turn it in ANY direction but with not much force. If you feel it is getting tighter, turn the other way and vice versa for tightening.
You do not need to disassembly the whole hotend - some hub wrenches (? in Germany ist's called "Nabenschlüssel" and ist used for bicycles) do have this pins for two hole drive ("Zwielochantrieb") and the space with already mounted hot end is enough to use ist and adjust the screws.
It is obvious you know what you are doing with this 3D printer. But, I can’t watch you videos as the frame view is always moving. Makes me nauseous. Really, take a course in have to record video. Movement matters. Lighting matters. Thanks and will return later and hopefully your videos settle down and not make people seasick.

Great job! My tronxy pro had same issue!

Exactly what I was looking to find, thank you. I don't get why this simple process wasn't included in the manual.

Thanks for the video. My X5SA Pro has one of the carriages too tight as well. I haven't tried the steps your outlined yet. But now I know what to do.

Appreciate your videos! They are very informative and helpful! Hope you keep making them :-)
I will be soon as I was busy, plus I am making a cheap enclosure for printing ABS and ASA filment.
2:30 How to adjust.
I also had rediculously tight rails and no instructions on adjustment
