I'm more than comfortable in, as mentioned, tearing down and doing overhauls on my locos. That's something I know and it's a simpler than simple mechanism. I run in DC, so it's even simpler. No sensors, no gobs of congealed plastic jamming in tubes, just plain and simple machines that are very cooperative when I make them do stuff. I give them juice, and they work. A 3D printer is another beast altogether. Tubes and pipes and heaters and sensors and a whole lot of sophistimicated doohickeys and diddywops. I work in electronics and do some pretty high-tech stuff at work, but for personal stuff, I'm a bit of a Luddite. 2012 non-smart flip phone Luddite. Maybe it's because of my job that I'm wary of complicated stuff. As they say, the more you complicate the plumbing, the easier it is to stop up the drain. I am, however, doing research on what are the highest rated in reliability vs cost, both out of the box and in long-term use. That might make me swing back the pendulum, and if sufficiently wallet-friendly, I might risk it. Might.
You will be just fine once you take the leap. actually 'leap' is too strong of a word, how about the next step in model railroading... Sumner
Good news - my printer head came in and I was able to get the Kobra up and running. Now for the reality of the situation. I mounted the head, printed some clamps and finished the last drawer for my LED holder, then - NO POWER! Once again, I have lost complete power on this second machine. Fuse has been checked and is good. All the normal checks have been done, such as checking my extension cord and power to my outlet. I was starting to think it must be operator error, but I just cannot wrap my mind around what I could be doing wrong to blow the power source on this unit. Everything I check is fine, except for my printer. I am calling this machine dead. I have had zero success with Anycubic. I have officially given up!
The only thing I can think of besides the more likely answer is possibly the voltage from the outlet is funky.. However, in reality it's probably caused by a cheap power supply. I tried to see if these were "Meanwell" power supplies in the K2s, as a lot of 3Ders swear by them, but on the Anycubic site their instructions for replacing the power supply on a Kobra 2 show them swapping out a Janco power supply. I haven't opened mine up to verify, but I can barely find any information on those - so translation (IMO): cheap and nobody is raving about them like the Meanwells. Now you got me paranoid that mine's going to blow out any second Honestly I haven't been very nice to my printer to date - it prints in the garage where temperatures out there get up 120 F frequently, add to that the electronics get hot anyway with the heated bed, nozzle, high voltages and I'm just asking for trouble. Yet - it's faithfully still chugging along. (fingers crossed!) Mike
I am glad you are having success. I have spent more time repairing my printer than printing part. I just do not have time to be constantly repairng this printer. I will just call the purchase a loss, as I simply have lost any desire to repair this thing again.
