I am glad I could help
I will look into that.
I am still having problems, with the prints messing up, I now know its ether the computer or software, and here is how I know, long story
-------------------------------------------------------------
I had wanted to try printing with Bluetooth, so I got this
http://www.amazon.com/gp/product/B0093XAV4Uits a cheap $11 Arduino Bluetooth module, the one I got in the mail was a JY-MCU v1.06, and I was unable connect when attached to a USB TTL Serial cable, I used the TTL-232R-3V3 listed on this page:
http://www.ftdichip.com/Products/Cables/USBTTLSerial.htmand tried to connect with HyperTerminal in Windows, but it never connected, and would never reply to commands, so I looked on the Internet and found this
http://mcuoneclipse.com/2014/03/30/getting-bluetooth-working-with-jy-mcu-bt_board-v1-06/the v1.06 version of the JY-MCU Bluetooth module has a diode on the TxD line, and that blocks the connection, so I bypassed it with a jumper, then followed the directions here
http://reprap.org/wiki/RAMPS_1.4#BT_ExtensionYou type the commands into HyperTerminal or other terminal emulator, you may have to copy then paste the commands into HyperTerminal.
- Code: Select all
AT
AT+BAUD8
AT+NAMEORDBOT
AT+PIN0000
and it responds with
- Code: Select all
OK
OK115200BAUD
OKsetname
OKsetPIN
The command AT+NAME is optional, and the command AT+PIN is optional, I believe the default pin is 1234.
After I finished configuring the JY-MCU Bluetooth module I then installed a Logic Level Converter converter I got from
https://www.sparkfun.com/products/11978I did this because the Arduino Mega UART communicates using 5V but the JY-MCU Bluetooth module communicates using 3.3V.
It looks like Sparkfun no longer sells the Logic Level Converter converter I used but this might work
https://www.sparkfun.com/products/12009Now cover any exposed places on the Bluetooth module and Logic Level Converter with heat shrink or electrical tape, then you set software to use one of the COM ports that was created by the Bluetooth connection and it should work, I used Cura to print with and it did work.
BTW to update the firmware you still need to use a USB cable.
-------------------------------------------------------------
I still had some prints mess when using Bluetooth just like when using USB, so I thought maybe the stepper drivers are getting hot, so I printed this up
http://www.thingiverse.com/thing:153849but it did not help.
-------------------------------------------------------------
I even upgraded the power supply with this
http://www.amazon.com/gp/product/B00D7CWSCGand used this to attach the power supply to the makerslide
http://www.thingiverse.com/thing:50775just make sure not to block the fan, also make sure the M4 screws you use with the clips you printed out are not to long.
I did not honestly think the power supply was the problem, but I wanted to replace the modified ATX, it looks better, makes it easier to move, and when using a In Line Cord Switch makes it easy to turn OFF/ON
I also printed this, I think, to cover the power supply terminals
http://www.thingiverse.com/thing:113525my prints still messed up,
-------------------------------------------------------------
So next I tried printing with the SD Card, and it printed perfect, so I tried a few more prints with the SD Card, and they all print perfect, next I will try a different computer and see it that works.
