Unresolved Printer stops printing

Ok Guys , this is a new issue with my printer and i would appreciate if anyone can help

one of my Robo R1 printers, stops in the middle of the print. I would say around first 3 min. I use Repitior and its weird that right after it stops the software that counts down the print remaining starts to count fast. Its been doing this randomly for the past 3-4 days. I have no idea where to look for to fix it. can you help ?

 

Could be a bad model / slice. I know I experienced that when I first got the printer, but that was with matter control. Changing the slice settings (infill) usually worked. I always just chalked it up to buggy software.

 

Also printing from SD is usually a good way of preventing this. Repetier host supports this as well.

 

I would occasionally have this issue prior to doing the LCD screen upgrade and saving everything to an SD card and running the print from there.

I know it's essentially a USB power issue for some computers, but I figured I'd go ahead and set things up so the printer can drive itself since the point is to be able to start a print and go do something else while it runs.

 

Can someone explain if i do not have the LCD screen how can i run it from the SD card ? Do i save the Gcode on the main directory of the SD card and then plug ? then what ? do i need to hit any button ? No idea !!

Thank you i did the SD printing and the same problem happened. Does this mean something in the printer is wrong ? How do i know what is the problem ? Could it be the Electronic board ? This is really annoying me

 

the thing is i am printing my models for more than 5 months and never issues. in fact the onther robo that i have is printing just fine with the same method. This one is working randomly and it started last week. I just printed using the USB cable with no problem at all. !!! before that i got one that failed . I know its not the models for sure. i don't know what is happening

 

Can you please tell me how the refreshing of the firmware works ?

 

If you had an lcd controller you might get a more detailed error message. I've had a couple failed prints with "temp fall error" on the LCD which is literally "temp dropped too fast" which makes the printer stop.

It usually was because the air conditioner came on for me, though this should be fixed after I set up my enclosure.

 

if it has to do with the firmware update shouldn't both printers act the same way ? since i am controlling both printers from 1 PC ? the other one works just fine. Also if the temp was going down , i could see that in the software controller but that dosn'tshow it is dropping. How do i make sure the fan for the RAMPS is working ? is it showing somewhere or i have to disassemble the bottom and look manually ?

 

I had a wire that was not connected from the factory to the power supply. it was just resting on it. So I got intermittent craziness.

 

no i am not sure, is there a way to check the firmware version ?
