Hi there, The graph and results can not be edited directly in the software. But the data is stored into a flat file that can easily be exported to Excel (or any spreadsheet editor), to be edited and graphs generated. Thank you for your interest!
Hi @@cnccams1428 , Please download again the Zip archive from my website, you will find the arduino file named "sketch_CamWerks.ino" in the camwerks/arduino folder. Please follow the instruction on my website as to how to debug/make sure your arduino is properly flashed and replies to the requests sent to it.
Hello and congratulations for your project!! I'm trying to make a camshaft bench based on your project i have replicated everything from the electronics as you describe in your site but when i click start measure the stepper does one step end stops. Do you have a clue what is happening? Thanks in advance
Hi @thanassis94, Thank you for your comment,! Actually, you're not the first one to encounter this issue. I had never seen it myself, until last week when I had to measure a camshaft for a friend of mine... For some reason, all of the sudden, crash after first step. Damn. I implemented a quick-and-dirty workaround into the code and uploaded the version 0.2 on my website. Please download it and let me know if it fixes your problem. And share some pictures of your bench, too! ;)
I think you have an error in the way you are measuring the camshaft... the "lifter" part is artificially adding to the lift curve in the area between when the lift is beginning to just before top lift... unless the lifter part that you have added to the calibers is an exact representation of the lifter used with the cam ( same diameter) it will distort your measurements.. to avoid this when measuring the cam you should use a roller (fx a roller tappet) that is centered on the camshaft center (the lift is radial through the center of the cam and the roller) this will give you one contact point that doesn't move off this center line
You are right, but I do use as a "lifter part", non only a representation, but an actual lifter identical to the one in action in the engine. So I get the actual figures of the camshaft, the exact way it works inside the engine. Thanks for your comment!
Hi, Please read the instruction on my website ; you probably have not installed the Arduino Serial Command library on your IDE (it's a USB communication library), as described in step 1.1. The download link is provided in my article ; you'll need to unzip it and drop the folder into your libraries folder (e.g. My Documents\Arduino\libraries, on Windows).
Hi Debbie, I've been asked multiple times to offer a commercial version, but between family and work I really, really can't find time to work on such a project. That's why I propose everything as open source, for people to make their own (I know a few did!). Thank you for your comment! :)
I am working on my own version of something similar. I got inspiration from your video for my project. Endgame for me would be measuring movement directly at the valve compared to the piston position in the bore. Measuring the camshaft profile is good information. Measuring at the valve takes into account all the other variables such as rocker ratio, lash, lash cap diameter, follower diameter and such. many things affect what is going on at the valve. I like that you included a follower in your setup. My setup is not nearly as refined as yours th-cam.com/video/GbXTes_7P3w/w-d-xo.html

hello Mr., can the software be edited graph from the results of measures cams
Hi there,

Thank you for your interest!
I tried downloading the caliper communication to Arduino very difficult, do you have a link for me to download, is it difficult to assemble the device
Hello mr I already installed your software how to connect to arduino, what files should be uploaded to arduino thank you

I am looking for a sketch file shamwerk.ino not find mr
Hi mr, do you have email, I have copied the arduino comand file to the library folder but there is a notification
Mr How do I flash the arduino, now my arduino is already connected to the PC, but I can't find the sketch_camshwerk.ino file in the folder

Ok as long as you are aware of this small boost in cam timing due to this geometry
PS. thanks for a quick answer and cool project
Do you share your arduino code for the cam measurement
Yes, follow the link in the description to the complete build article. Java and arduino code freely available for download from there.
Hello, mr I've found the camswerk skestch file, but it can't be uploaded on arduino, error on serialcommand.h, thanks

Hi me, I have downloaded the arduino serial command and can't, there is a notification as if the memory is only 20%
You should sale it
