I am having a problem with my 1.1.9 firmware.
When I have AUTO_BED_LEVELING_BILINEAR enabled the printer homes Z in the wrong direction - the nozzle goes up instead of down when I issue G28.
With AUTO_BED_LEVELING_BILINEAR disabled the printer homes as expected, but that means I can't auto align the bed. Setting Z_HOME_DIR to 1 does get it moving in the right direction, but I'm then stuffed for

Problem SOLVED.
This turned out to be a multiple cause issue. Only by finally finding the correct configuration did I get the BLTouch working. These causes were:
1) Whilst I purchased the HicTop 3d board, there was a lot of confusion about which board definition this was within Marlin. The advised HicTop Marlin download worked great, but it was an earlier release which did not support the BLTou

I have managed to get the BLTouch probe working, nearly.
When I home all axes with a G28 X & Y do their thing, then the probe goes to mid-table. The probe deploys. Z goes down and it triggers the probe. I have double probing enabled so it rises - and then waits a couple of seconds before going down again. But it does finish.
I have configured bilinear bed levelling. When I select that with

Just saw this.
I have 3 BLTouch in use. Very happy with their performance. I'm using MKS 1.5 running marling 1.1.x RC8. Took me FOREVER to get this configured correctly.
I'm assuming you have endstops for x/y axes as well, correct? Z homing won't happen without those.
I will share my Marlin settings. The only issue I have right now is that during bed leveling probe, Z does not go

I've given up with the BLTouch and am now using a capacitive sensor instead. It works remarkably well, detecting the print surface about 4mm away.
Whilst I had tried to use a capacitive sensor previously, that had failed due to it needing to touch tyhe print surace before making the detection. I have since discovered that was due to the capacitive sensor being driven with a low 5v supply. When I

And to make matters more difficult... Some of the BL-Touch clones actually have an inverted signal. If you have a real BL-Touch, you can ignore this message. But if it is possible you have a knock off, you may need to invert the signal.
I actually have 3x bltouch sensors. The one currently in use (and not triggering) came from Antlabs several months ago. However I received 2x chea

In your config.h
Quote#define Z_MIN_PROBE_ENDSTOP_INVERTING true // set to true to invert the logic of the probe.
I think you need to change this to false as the bltouch is like a NC endstop and gives a 5mS +pulse when triggered
Have done and it makes no difference. The probe drops as expected but never triggers when the probe is pushed.

It isn't triggering. When I put the printer in homing mode, X & Y do the necessary, however the BLTouch probe on Z does not trigger so I have to power off to stop the Z crashing into the bed.
There is probably a gcode to stop the homing but I haven't looked for that yet - power cycling does what's needed.

Everything is now nearly working. The response from the M280 commands are as expected. However the probe status remains fixed at activated - it doesn't change regardless of any instruction.
I imagine I've got a configuration issue relating to the BLTouch sensor but have so far failed to identify what the issue is. I have tried changing the options relating to ENDSTOPPULLUP_ZMIN, Z_MIN_PROBE_ENDS

You can't have repetier host connected to your printer at the same time you are trying to send firmware through arduino.
You must disconnect repetier host from the printer before sending from arduino.
Aha! The old Makerbot service problem where the Makerbot software clinged onto the printer connection and required disconnection as a specific step. I didn't think of that so many thank

Thanks all - some good info there which I am very grateful for.
I downloaded and installed Repetier host. Now Arduino is refusing to upload new firmware to the printer - it compiles fine but fails with a timeout on upload. This is new, previously I had no problem with uploading. Have removed and reinstalled Arduino thinking that would reinstall the driver, but it didn't. I can see the printers p

Thanks for that.
Is there a way to send gcode commands to a 3D printer interactively? I have Cura and Simplify3D available but they don't appear to offer interactive options.

I have recently built a Hictop 3D printer:
All working fine. Have tried to add a BLTouch sensor but have run into difficulty.
Have replaced the main control board with an MKS 1.4:
Wired according to instructions:
Having recompiled and uploaded laterst Marlin v1.1 the BLTest menu option causes the BLTouch to pulse several times. It starts up with a self-test, so I suspect the hardware co
