SainSmart 2-in-1 3D Board cant upload firmware please help

by dmkmedia

has anyone got a SainSmart 20-029-129 2-in-1 3D Printer Controller Board https://www.amazon.co.uk/gp/product/B00PVF5SWE/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1
this is my second one now as I sent the first one back.

I just can not upload my firmware to it... I can connect to it via USB and all I get is a list of numbers saying
T0 980 T1 976 T2 1024

i take it this is just the raw data from the temp sensors but i cant upload firmware with Arduino all i get is a long pause after compiling as if it's uploading but after about 5 mins it just says there has been an error uploading the firmware

by harddrv1

Having issues with my Zonestar P802M I need a step by step on reinstalling the firmware Through Zonestars Upload tool I get time out errors and through Arduino IDE I get errors as ell please help My printer is useless at this point, It started by simply not printing I had full control of printer either via octoprint or the controls on the printer however prints would immediately cancel at the start of print. I the read I may have a firmware issue so I tried to update it I tried Zonestars Firmware Upload Tool and Tried the File "P802MR2_ZRIB_V15.hex" the .hex was not entered as per instructions, after several failed attempts (and too many beers) I tried the file that came with it labeled (Z6_V3.hex) to my horror this file did work and now I cant access my printer at all the display it all blacked out and no buttons work nor is it controllable through octoprint. I would really love to get this fixed it has been several months please help me Thank You.

Glues for PLA?

by ghstgry

I've been having a time of it trying to find a glue that will bond two pieces of PLA-printed material together. I've tried all kinds of flavors of CA glue to no avail, including but not limited to Loctite and Gorilla Glue, in both thin and gel formulas.

Do I need to prep the surfaces somehow? Or is there a preferred method/adhesive for PLA?
