TEVO BLACK WIDOWDear Black Widow user. Temporary solutions……and important information…for new bies…. And so called pro’s. Tevo delivers two Black Widow versions The standard version is equipped with Marlin RC7. The BL-Touch verrsion is equipped with Marlin RC7 BL-Touch. These machines do not come with a part to mount the BL-Touch to the machine. So the machine can not be used this way when ready. To overcome this problem, you have to downgrade the firmware first to BW_MarlinRC7_With_BLTouch Disabled.zip which can be found in the file section of this group https://www.facebook.com/groups/TEVO.Black.Widow.owners/files/ This version uses the original Z-min stop. When the machine is working and calibrated you can print the BL-Touch mount first. You cant mix firmware using the BL-Touch and the magnetic Z-min endstop! It is one o nor the other. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Currently (October 2016) there are many reports that the Autobed levelling in Marlin RC7 is not working correct. This has nothing to do with the BL-Touch itself but is Marlin related. Download from the same file section the Marlin _RC6_Black Widow-BL Touch.zip version The reworked RC6 BL-Touch version does not have lesser functionality as RC7 concerning printing and print quality. The BL-Touch Mount file can be downloaded here. http://www.thingiverse.com/thing:1761761 Large version. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ The latest versions (september 2016) come with a E3D V6 clone heater unit. Before use it is adviced to check the unit for sealing by the following link. http://wiki.e3d-online.com/wiki/E3D-v6_Assembly ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ If you want to use an object cooler fan you need to put two extra (+) and (–) wires in the drag chain. These wires should come from the MKS V1.3 board FAN connection. The fan speed on this connection is controlled by G-code PWm from 0 to 255. If you order a BL-Touch version you get two extra cables which you need to put in the drag chain.

If the voltage is set to 110 Volt in a 220 Volt location then the heatbed might give problems with heating. wires. The powersupply comes standard set at 220 Volt.

To align the Z bar. shifting layers and other unexpected movements make sure the LCD cables are not running over the fan or near the fan of the power supply. If this is not the case use a hairdryer and warm the heat shrink and form it to a circular round shape. Open Repetier. No need to proceed if the selftest is not working! Solve this first! If the BLT starts to flash red. The heatshrink part should be uniform round. BL-Touch (BLT) selftest always start with this first!!!!!!!!!!!!!!!!!! 1] Disconnect the USB cable. Make sure the machine is detected by the software! Send the following codes to test the BLT: M280 P0 S10 . If it does not go in and out check the 3 wire cable as it does not get 5 Volt power. The BLT pin should go out and in 2 times and then the light should be solid red.TEVO BLACK WIDOW Test your BLT when it is connected this way.zip .0 mm from tip nozzle to bottom BLT (not the pin) Move the Z-axis upwards and make sure the head is above the middle of the heatbed!!!!!!!
