TEVO Black Widow - Read This First - New Bie Manual V6

TEVO BLACK WIDOW Dear 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.

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

TEVO BLACK WIDOW ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ When you are printing direct from a SD card and you have random problems during printing like reverse extruding, 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. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Tip! To align the Z bar. Use two soda or beer cans as shown in the picture to make both sides level.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ If you need to hook up the BL-Touch this is the correct connection schematic. You can only connect one Z-min endstop connector!

TEVO BLACK WIDOW Test your BLT when it is connected this way. BL-Touch (BLT) selftest always start with this first!!!!!!!!!!!!!!!!!! 1] Disconnect the USB cable. Power on the machine. The BLT pin should go out and in 2 times and then the light should be solid red. If it does not go in and out check the 3 wire cable as it does not get 5 Volt power. No need to proceed if the selftest is not working! Solve this first! If the BLT starts to flash red. It might that the top of the BLT pin is deformed as it ran into the heat bed during previous test. Remove the hexagon screw at the top of the BLT. Remove the pin and check the top. The heatshrink part should be uniform round. The picture shows a deformed top part. If this is not the case use a hairdryer and warm the heat shrink and form it to a circular round shape.

Assemble the BLT again and make sure the hexagon screw is flush with the top of the BLT. 2] Connect the USB cable to the machine. Connect the BLT cable on the correct spot on the MKS V1.3 board. Make sure the correct firmware is on the MKS V1.3 board. We advice Marlin _RC6_Black Widow-BL Touch.zip . Open Repetier, Pronterface or any controller that can send G-codes on a command line. Make sure the machine is detected by the software! Send the following codes to test the BLT: M280 P0 S10 ; pushes the pin down M280 P0 S90 ; pulls the pin up M280 P0 S120 ; Self test – keeps going untill you do pin up/down or release alarm M280 P0 S160 ; Release alarm We assume the BLT is correctly installed on the machine 8.0 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!!!!!!!

Calibration. These instructions were written to explain how to calibrate using a computer connected through the USB port to your printer. This process also assumes that the EEPROM has been enabled in Marlin. M851 ; note the number M851 Z0 ; set the offset to zero G28 G1 Z0 The LCD display should show Z = 0 From the machine LCD display go to the Menu then Prepare/Move axis/0.1mm/Move Z Now move the Z axis slowly down until the nozzle is the right distance from the build plate (folded piece of paper or thin card). * Note the Z axis value on the display it should be something like -1.5 M851 Z-1.5 ; to set the offset you got in the previous step. M500 ; Stores the values in EEPROM so that it is not reset when you power the printer off and on. If you find that you need to increase or decrease the gap then do: M851 Z-1.4 ; this would make the gap bigger M851 Z-1.6 ; this would make the gap smaller M500 ; to save the value to EEPROM (remember the -1.4, -1.5 and -1.6 are just examples , yours will be different) +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Arrange the LCD cables away from the fan of the power supply in the controlbox. This prevents users of SD cards that the data is corrupted while printing. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Tevo machines do not come with any driver/slicer or other machine related software supplied. For slicing (preparing a file and printing a .stl file) use Cura 10.5.4 this is a full function free software with full slicing and printing capabilities. Use this as standard slicing software for the first prints you make. If this is your first 3D printer do not use the Cura 2.X versions yet as it does not support easy access to start/end G-code. https://ultimaker.com/en/products/cura-software/download-request/74 Start code

For all newbies best advice is not to use the BL-Touch yet. First install BW_MarlinRC7_With_BLTouch Disabled.zip firmware which uses the original magnetic Z-min endstop switch. Get used to manual bedleveling and later install the BL-Touch when you feel comfortable and then use Marlin _RC6_Black Widow-BL Touch.zip firmware. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ To have a flat printing surface use a 250x400 mm – 4mm thick regular window glassplate. No need for expensive Borosilicate or Tempered glass. Do not use binder clamps/clips to mount the glassplate to the heatbed. Use 0.5 mm silicone thermal pads inbetween.

TEVO BLACK WIDOW This prevents the glassplate to move and gives easy placing. Use Auqanett hairspray or 3Dlac for correct bonding of the first layer. Due to the thickness of the glassplate you need preheat the heatbed longer so the glassplate can receive the radiation heat from the heatbed. Approx. 5 minutes extra. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Warm up time of the heatbed from 20 to 80 degrees Celsius takes +/- 3 miutes time. If your heatbed takes much longer check the 110/220 Volt power supply switch for correct setting. And check by handtouch if all parts of the heatbed are equally heated. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Disclaimer: This document is brougth to you by Jupa Creations
