Hi guys. Looking for some help.
I installed the smart display and been trying to print from the sd card but doesn’t like it
Changed the file extension to gcode. Anything else that needs to be done? When running the program reads it and does nothing.
Thanks for your help.August 5, 2016 at 2:55 pm #15702
Need to clarify. Tried to mill and changed the nc file extension to gcode.August 5, 2016 at 3:03 pm #15704
Can you see the files on the card, if not what size is your SD card?August 5, 2016 at 3:09 pm #15705
Yes, with gcode extension. Nc cannot seeAugust 5, 2016 at 3:09 pm #15706

You can rename your files whatever you want. There is a setting in estlcam to change the extension of the saved file. Nice and easy.August 5, 2016 at 4:09 pm #15710
But haven’t answered if there is anything else that need to be done besides changing file extension.August 5, 2016 at 4:11 pm #15711
I just needed to change the extension to .gAugust 5, 2016 at 4:13 pm #15713
Thanks. I might have a bad card, happened before.September 10, 2016 at 10:02 am #17501
My SD card is not recognized either. I can only 3d print with my laptop tethered to the RAMPs with my Short USB cableSeptember 10, 2016 at 10:52 am #17503
Is your card formatted with fat32?September 10, 2016 at 11:31 am #17507
Yes it is 16gig FAT32. It works fine in my other 3d printer in it’s smart controller.September 10, 2016 at 11:40 am #17508
I like your design and engineering on the MPCNC. I ordered your hardware and electronics and printed my own parts. I’m overall quite pleased, so my hat’s off to you. I just cant get the darn SD reader to work so I can free up my laptop. I’m stumped. I’m hoping it’s something simple I can fix.September 10, 2016 at 12:18 pm #17510
Since you have 2 screens switch one of them so you can verify where the problem is. Its either in the screen or somewhere else, but if you cam narrow it down a bit we can find the issue quicker. I’ll be in and out all day, building some shelves in my garage so I should be able to help every so often.September 10, 2016 at 5:24 pm #17530
Okay so I finally got some time to mess with this and I uploaded the firmware for the discount smart controller from your website and used the other LCD (the little one) and it works and recognizes the SD card. So the large LCD one seems to be the issue.September 10, 2016 at 5:42 pm #17536
Everything else on the screen worked, just didn’t read files(on the large one)?September 10, 2016 at 7:39 pm #17545
Yes everything else worked.September 10, 2016 at 7:47 pm #17546
Check all the solder joint around the card reader there are only 11 or 12. If you got it from me you can send it back in.September 10, 2016 at 7:48 pm #17547
You kept the same connector and wires right, to make sure the issue is in the lcd screen board and nowhere else when you did the test swap?September 10, 2016 at 8:05 pm #17548
Yes I kept the same wiring and all that. And yesI got everything from you except the EMT and printed parts. I’ll check the solder joints…September 10, 2016 at 8:22 pm #17549
I appreciate that but idk if it’s worth the shipping to send it back to California from Florida.

Those last two pins look suspect, if you can solder hit them real quick if not no problem. If you send it flat rate small box it’s $6 If I sent you a bad one I’ll reimburse you for your shipping.September 11, 2016 at 4:48 am #17558
Okay Yea after looking close at the picture I agree. I give it a go with the solder Iron when I get a little time and I keep you posted.September 11, 2016 at 10:37 am #17563
I’ve noticed on some of mine that sd only works if the card is inserted BEFORE power is applied to the ramps/mega. Others let me hot swap auth no problems. Minor inconvenience so never bothered troubleshooting.September 12, 2016 at 7:50 am #17600
It turned out after re-soldering the last two pins I now have a functional SD card reader. Good call.and good info for anyone else having SD card issues.September 12, 2016 at 7:51 am #17601
Sorry for the hassle, thanks for fixin it!September 12, 2016 at 7:57 am #17603
No worries. One can’t expect a project like this to be perfect. It was a learning experience. I’m trying to post a photo from my phone but the file size is too big. Anyways I appreciate your fast response and insight. I think you are doing pretty good for seemingly one guy. I have no complaints your mpcnc works perfectly.September 12, 2016 at 8:05 am #17604
Sorry to hijack, but question for Ryan.
On the smart display, what is the value of the resistor that you retrofitted?
I have had one of these for a while, and have just put up with the barely readable display, so I think I have the problem you solved.September 12, 2016 at 8:44 am #17610
I don’t think the value actually matters too much, Pretty sure it was about 100k pictures are still up of it on the shop page for the screen. It just needs to be more than what it is.
