@dc42 , thank you. If I understood it correctly M558 P8 C5 ... would work for me? I use firmware 2.05

I am developing an effector similar to Smart Effector for using my dc42 Kossel as an automatic solder paste dispenser. I use LSM6DS3 accelerometer chip as Z probe. At the moment it works pretty well for me and triggers an output within 1-2 milliseconds after plastic TT needle touches the bed or board on it. I use E2Stop input on my Duet2 Internet controller as Z probe input, P4 probe type in M558 command.

Everything worked satisfactory but there is a problem: time delay between my probe output and start of reaction the system is about 9 milliseconds. It is somehow long for my case (plastic needles is a delicate matter). As I understand it all Z probe inputs have some sort of filtering on them except the dedicate Z probe input on Duet2 board at P8 probe mode. But I don’t disconnect the Smart Effector when using my own effector, so if I want to use this dedicated input I need some sort of combining circuit.

So that is a question: what is the time of reaction difference between filtered and unfiltered inputs and is there any sense to mess with an additional circuit?

@jay_s_uk said in magnetic PEI sheet - will it interfere with smarteffector?:

I use a whambam system on my predator (PEI sheet with magnetic base)

Does you print nylon filament? And if so is there any issue with adhesion? Thanks for advance.

I have not got removable PEI sheet (but consider one as a replacement) but I use geckotek3d spring steel sheet on magnet base with smarteffector for about 3 years and have no problems with it. So IMO it should be the same with PEI sheet on magnet base. BTW I would like to know how will PEI be working as my geckotek3d cover has worn and they do not produce the plate anymore. HTH

Thanks everybody who response to me! Your help is appreciated. I might contact Olsson directly but not sure they know smart effector very well. Accordingly to BPisLife remark now I am inclined to try hardened steel nozzle first.

@chrishamm : Thanks for your response! Was there anyone at the show that used Olsson Ruby with direct contact Z-probe?

I have been successfully using standard brass nozzle in E3D V6 hotend for some time and was happy. Now I am going to try some of advanced filament like CF filled nylon. They are abrasive so more hard nozzle is the must. I would like to use Olsson Ruby but not sure how it will work with Smart effector. Does it survive impacts with the hot bed during auto-calibration? Maybe someone has an experience with such combination.

As the topic starter I have just received a very generous offer from Haydn willing to send me a set of ball studs from the new batch free from charge. What's an exceptional service! Many thanks to Haydn for his hard work of improving already excellent design!

Thanks for your info!

@dc42:

I don't advise connecting multiple fans in series, because there is no guarantee that they will divide the voltage equally, especially if they are mounted in different ways so that one experiences greater resistance to air movement than the other.

Me too, I just would like to know if noctua's fans can be controlled by supply voltage PWM to use them with 12V power as they are very low noise and long lasting fans.
