Another thing.... could I get errors if the sensor is positioned on a point of the bed where there are white lines or white text or withe graphics over the black coat?

Hello David,
I have a E3D Bigbox printer using one of your sensors which for reasons that baffle me has stopped responding!It triggers with pretty nearly everything I try: clear plastic, black paper, even a mirror but it refuses to trigger with the glass and bed though either of those on their own will make it trigger!I've spent nearly 3 days fiddling without any success.Hope you can help.
Mark.

The black paper under the glass works. Is there any reason why the behavior should have changed ?There is one other Bigbox user who is having similar problems where his sensor only triggers on parts of the bed!

Hey David,
i bought the ir sensor and can't really get it to work. I'm pretty sure the error is my fault though. So my setup is a Kossel XL with Marlin firmware. I have a glass bed with a heat spiral glued to it from the bottom. When the nozzle crashed into the bed I thought the problem is the heating spiral which probably is too reflective. So I placed a black CoroPad ontop of the glass bed to prevent the reflections of the heat spiral to effect the sensor. Still it crashes into the bed. Sometimes with the first probing point...sometimes after the third or fourth. There are two things I just found out:
1. when i power on the system only over the USB-Port the LED flashes four times. On the other hand if I power it on with the 12V supply first, it flashes only twice. (like I think it should)
2. After it flashes twice I home it via G28. Then when I send G29 right before the first probing point the LED lights up constantly dim.
Any ideas what the problem could be? Sending M119 returns me a triggered endstop when close to the bed manually.
Thanks for any help!!!

Hey David,
First of all, thanks for the fast reply!! Awesome, really!! I think i'm fine with using the 12V power supply, so that's not really an issue. Now after some more trials it works fine with the first 5-8 probe points until it hits the bed. After it hit the bed it has the LED constantly lit up, so i guess that's the reason for crashing. Waggling the wires doesn't change the LED. After homing it works again for 5-8 probe points.
Any further ideas or is an replacement inevitable?

I'm glad you got it working.
I am considering supplying these boards with the straight connector already soldered on when I have the next batch made, because this is what most people use and it avoids the need for the customer to do any soldering.

I wonder if any one can help please.
I have been building a larger printer and have fitted a Mini differential IR height sensor. I an using a Radds controller.
I have used a pair of volcano heads on a chimera block.
Two weeks ago I had everything fitted and could home the 3 axis's. I could also do a G32 and all worked well. I have heated the hot ends but never put any filament in either of them.
I then went away on holiday for a week, I arrived home and eagerly switched the printer on the LED blinked twice so all seemed fine. I homed X, homed Y then pressed to home Z, the nozzle crashed into the bed I switched the off.
I restarted the printer and the LED blinked twice. i put a sheet of paper under the sensor but the LED did not come on. I have restarted the Printer a few more times and the LEDs blink twice on each restart, but it will not work when anything is put below the sensor.
I Looked at it through a video camera that i know picks up infra red and cant see the LEDs on, If i point a TV control at it the LED flashes red.
What can i check to see what is wrong?
Regards
Martin
