Longshot: Need Marlin & Configuration.h for MKS Base v1.5

by Dingoboy71

Hi there,

My Wanhao/Monoprice MS v2.1 has been somewhere between DOA and life support for a while (but let's not get into that). I've replaced everything but the Melzi board & I've decided I don't want to spend good money on another Melzi. I happen to have a brand new MKS Base v1.5 and 2.8" TFT LCD in the drawer. As I understand it, this will use the same firmware as a standard Arduino Mega 2560 + RAMPS v1.4.

Wondering if anyone who is running Marlin would care to share their Configuration.h file, as I've never gone through one line by line- I've only followed tutorials when building other printers to change a line here & there.

Odd printer Jam Issue driving me nuts. Someone please help me :(

by PIXeL_92

Hi All,

I have been having an issue I have never had before. I have had issues in the past I have been able to resolve via touble shooting but this has got me stumped and I was hoping someone could share some insight.

Issue -

What will happen is it will print the first few layers fine (lets say 15-30 minutes of the print) and then it will start jamming and cause the printer to under extrude.
When this happens I will kill the print and then push the PLA down and pull it back up to remove it, then will cut about 5 CM off the end of the PLA and put it back in and manually push it down the nozzle and it comes out fine again and it will happily print until the next jam.

It looks like it is solidifying in the tip of the nozzle and causing a build up to the point it blocks, see the pictures to see if you agree.

Set up -

Wanhao i3 with Brace installed
All Metal Hot end (MicroSwiss)
Upgraded cooler (dii3 i think its called)
New Fan on side of heatsink

Failed Soultions -

New Heater Block
Re-installing All metal hot end exactly how instuction dictate
Cleaning the nozzle and feeder tube
Re leveled the bed several times
Increased printing temps in 5c increments up to 235c
Decreased retraction settings to 0.5mm and 20mm/s
Cleaned black finned metal heat sink (was a little dusty)
Gave the fans a blast of air
Installed two different new extruder gears

The GCode I have been trying to print has been printed on this exact same set up I would say about 130 times and I have never had a problem until now, nothing has changed in the set up.

Thanks in advance for any help. If you need any more info ask and I will try and provide

Maker Select 3D Printer v2 - Build plate no longer heating up.

by msmouse05

Well, after finishing a print and taking a break for about an hour to eat some lunch I went to start another and the plate wouldn't heat up. I tried turning it off and on again a few times but that didn't help, worth a shot. The temperature sensor is working, if I place my finger on the sensor it goes up and then back down when I take it off.

I've read a few threads on here about similar issues but none of those seem to be the problem. The wire on the bed is in good shape so I opened up the control box to see what was going on inside. I had read that things may burn up in there but from what I can see, everything is in great condition.

I did come across some articles on installing a MOSFET board with this printer to avoid the issue I'm having, wondering if doing that now after it's failed would fix the issue.

I can't see any visible issues and not sure what is safe to try and take apart at this point. I did recently increase the temp of the plate from 60 to 65 when printing, but the manual says it's good to 70 so that shouldn't be an issue. I've had the printer for over a year, but it's only got about 10 days of print time on it so not a huge amount of usage. Any thoughts or suggestions would be appreciated.

EDIT: Issue resolved.

Well I ordered a MOSFET board and installed that and that has resolved the issue. After all the troubleshooting I could tell the wires were okay and the screw connector was generating power but it still didn't work. It was out of warranty so I went ahead and tried out the MOSFET board and it fired right up. Here's hoping it lasts, thanks everyone for your help.

Board Replacement Options

by Dakine83

Hey all, I'm experiencing some odd issues with my Maker Select v2, and I think it's due to the board. I'm getting random resets mid print via USB and SD card, though removing the auto reset jumper seems to have fixed this - for the moment.

Given all the bad reviews I've read of the melzi board, and the fact that I don't mind tinkering, I wanted to replace the board. This will also be good practice for when I build my next printer.

I've seen the replacement options here: https://3dprinterwiki.info/di3-mods/board-replacement-options/ but this hasn't been updated in 2 years. Are there any New/Improved options out there? I would prefer to go over"board" on this one than use a subpar replacement. I like the idea of a 32bit controller, especially if this will allow me to print better and faster off octoPrint, as the USB connection speed as it stands is kind of a bottle neck there.

Anyhow, whats the "best" option out there currently?
