My modulated IR/ultrasonic hot end board: request for feedback May 29, 2014 11:04AM |
Registered: 10 years ago Posts: 14,672 |
I've shipped over 50 of my z-height sensor + illumination + fan control kits, and I'm close to finalizing my new design for a height sensor (see [forums.reprap.org]). Before I do that, I'd appreciate some feedback from users of my existing board. So if you bought one of my boards and have at least tried to assemble and install it, please can you provide feedback, either in this thread or by PM. You might like to consider the following when composing feedback:
* Does you find that the height sensing gives repeatable results once you have calibrated it?
* Do you trust it to do the z-homing, or do you still set the height manually and send G92 Z0? Do you trust it to do bed compensation?
* Does the illumination work well?
* Does the fan control work well?
* Are you satisfied with the way the various cables connect to the board, or do you think it can be improved?
* Are you satisfied with the build quality?
* Do you think your kit was good value for money? [Please say which kit it was.]
* Are there any other features that you think could be usefully added? [The new one will have a led to indicate when the hot end heater is on, and I'm open to other suggestions.]
* Did you find the assembly instructions clear? [No need to repeat issues/suggestions that you have already reported and I have corrected.]
* Are there any other ways in which you think the board could be improved, perhaps to make assembly and installation easier?
Thanks in advance!

have used the ultra sonic only, repeatable at temperatures as commissioned, draft can be a problem

I trust the probe but not the temperature around it (moving air in work shop), so within working hours I do check the zero on paper
I do not use any bed compensation
Quote
* Does the illumination work well?
perfect
Quote
* Does the fan control work well?
right on temp. target
Quote
* Are you satisfied with the way the various cables connect to the board, or do you think it can be improved?
Yes perfect, with the heater and temp probe cabling up the x+ side of the hot end its all in line
Quote
* Are you satisfied with the build quality?
Couldn't be better
Quote
* Do you think your kit was good value for money? [Please say which kit it was.]
Kit 5, sure was

* Are there any other features that you think could be usefully added? [The new one will have a led to indicate when the hot end heater is on, and I'm open to other suggestions.]
not really...a small crash helmet for the IR? - nah...

* Are there any other ways in which you think the board could be improved, perhaps to make assembly and installation easier?
not anything I can think of

* Does you find that the height sensing gives repeatable results once you have calibrated it?
Yes. I have to recalibrate whenever I have taken things apart, but once set it works perfectly. Not sure about the precision it gives, but in any case less than 0.1mm.
* Do you trust it to do the z-homing, or do you still set the height manually and send G92 Z0? Do you trust it to do bed compensation?
It does nothing but Z homing in my case, and it does that really well. I got the bed "mechanically levelled" and do not need any bed compensation. I tried to get it to work earlier, but my "white taped areas" were too small so I couldn't probe on them without removing the binder clips, which made it all too much of a hassle.
* Does the illumination work well?
It works, but since I'm using that "BigBlur 360" behemoth, most of the light just gets blocked.
* Does the fan control work well?
It does. After the improved Z probe, this is the second best feature.
* Are you satisfied with the way the various cables connect to the board, or do you think it can be improved?
It would be nice with one big connector for the whole wire loom to the board, or have them angled for easier access. The current ones are a bit fiddly to attach/reattach if I need to take off the hotend.
* Are you satisfied with the build quality?
Yes. PCB and pre-soldered components seem very well-made.
* Do you think your kit was good value for money? [Please say which kit it was.]
I got the "full-blown" kit (whatever it was called, with the ultrasonic sensor). I can't say it seemed really cheap, but compared to the cost of the printer and how much better the Z probing got as a result of this upgrade, I think it's money well spent.
* Did you find the assembly instructions clear? [No need to repeat issues/suggestions that you have already reported and I have corrected.]
Yes.
* Are there any other ways in which you think the board could be improved, perhaps to make assembly and installation easier?
The little printed arm (in your git repo) to make the sensor work for X endstop was hitting the Z gears and stepper motor axle when z-probing (or printing the first couple of layers). I modified that to get a bit more clearance, I'll pass that on.
* Are there any other features that you think could be usefully added? [The new one will have a led to indicate when the hot end heater is on, and I'm open to other suggestions.]
None that I can think of off the top of my head.

Ormerod168 and jstck, thanks for your feedback.
I added sensorpad-modified.scad and .stl 25 days ago to [github.com], which I think should solve the problem for most users. Let me know if you don't think that one would work for you.

I had a kit 4 I think, I found it very professionally presented and constructed. It was easy to assemble and fit and worked first time.
The illumination is sufficient and very helpful, the fan control is fantastic and the Z zeroing also works very well, I have my bed mechanically level so only use it for z height setting which seems perfectly adequate for it's purpose, I have not tried to measure repeat ability as I just fitted it and put it to work
Over all, an excellent add-on and good value for money.

It probably would. I made the attached one at about the same time.

with white label it's working fine...
* Does the illumination work well?
I'm not sure about the position...
* Does the fan control work well?
I put the fan always on...
* Are you satisfied with the way the various cables connect to the board, or do you think it can be improved?
my dream is to get the card with the wires soldered on board
* Are you satisfied with the build quality?
it's OK
* Do you think your kit was good value for money? [Please say which kit it was.]
for a micro-production... it's OK
* Are there any other features that you think could be usefully added? [The new one will have a led to indicate when the hot end heater is on, and I'm open to other suggestions.]
let me dream... a small cam?
* Did you find the assembly instructions clear? [No need to repeat issues/suggestions that you have already reported and I have corrected.]
well done
* Are there any other ways in which you think the board could be improved, perhaps to make assembly and installation easier?
Thanks in advance!
Thanks David

I bought a pre-built Kit 5 from you.
Does you find that the height sensing gives repeatable results once you have calibrated it?
Sorry, never was able to get repeatable results with it for either X or Z homing. Really needed to recalibrate it every time I used the printer.
* Do you trust it to do the z-homing, or do you still set the height manually and send G92 Z0? Do you trust it to do bed compensation?
Have mechanical bed compensation. I now use a switch for X homing and set Z manually but am considering also using a switch on the Z axis.
* Does the illumination work well?
Yes very useful
* Does the fan control work well?
Yes very good not to have the fan running continuously.
* Are you satisfied with the way the various cables connect to the board, or do you think it can be improved?
I thought that your cabling was a great and much needed improvement to the standard kit.
* Are you satisfied with the build quality?
Build quality was very good.
* Do you think your kit was good value for money? [Please say which kit it was.]
Again pre-built Kit 5 and at an acceptable price.
Even though I have not had much success with the probing I am happy with the light, fan control, general tidiness etc. I have replaced my ormerod bed with an aluminium plate and also replaced the X axis with an aluminium one (both available through the forum). Realistically I think that these two upgrades have made my printer much more stable and would recommend anyone to do these upgrades first.
* Are there any other features that you think could be usefully added? [The new one will have a led to indicate when the hot end heater is on, and I'm open to other suggestions.]
The led showing heater is on is a good idea
* Did you find the assembly instructions clear? [No need to repeat issues/suggestions that you have already reported and I have corrected.]
Clear instructions and easily assembled.
Generally, I have been happy with the board but do not think I would swap to your new board at present. I think that I will wait to see what developments there will be in the multiple hot-end line. But I do want to thank you for all the software development you have done over the lst few months.
