Constant jam ups
Constant jam ups, and Byrd nests. Poorly design spool driver with only one 3-D printed TPU type bushing on the right side causes serious binding and shuttering when it does occasionally get traction. Most of the time it just ejects the filament without moving the spool and causes tangles. Also, does not support filament drying while printing as advertised.. No filament release button when filament jams inside AMS unit. I enjoy solving problems, but there’s very little that can be modified to fix these problems. For context- This was bought for a QIDI +4 printer which I’ve had constant problems with, mainly with the leveling system, especially with high temperature filaments. I figured Work around for some of the issues, but the machine is extremely troublesome and time-consuming to get to work properly.. QIDI has worked with me and has given me many new parts, including new plates and nozzles that were destroyed by the machine, however, it’s clear it’s a design issue because none of the new parts (peso sensors and leveling circuitry) make any difference. Though, having an excuse to tear the machine apart and put it back together, (kind of fun). I purchased the QIDI box, hoping it would solve some of software crashes it regularly has and G code anomalies, which stopped the machine for no apparent reason after it’s insanely long pre-print prep. THIS IS THE ONLY MACHINE OUT OF 6 PRINTERS that I have these issues with. So I’m certain it’s not operator error and still hope that a future update may fix the issues. FYI I put a heat shield over the leveling circuitry and installed a small fan at the bottom of the printer. Aimed at the leveling circuitry and that has stopped the plate crashes. And I watch the G code when it’s going through its very long pre-print routine. If there’s more than one or two retries on the leveling probe G code, I turn the machine off and start over… If there are no retries while the leveling probe is running, you will usually get a good print. Oh, and don’t even bother with the Z offset you’ll drive yourself insane. I learned to set it manually once a print started, and as long as you’re not doing high temperature filament it will usually stay about the same. So yes, it was a gamble for me to buy this QIDI box after all these issues and it looks like I lost again. If your new to 3-D printing, buy a bamboo, they work. Im not giving up on QIDI, but right now their price points don’t justify the frustration, And since this is not the first AMS ever design, there’s really no excuse for such foolish design flaws.
