Hi Phil,

I already flashed the TI board but because I don't have the display (which I already ordered), I couldn't see the output. There were no error messages, but I would be more confident if I could see any output ...
Can I use an "LCD Display and Keypad Shield" for Arduino?
If so, which pins to use in the shield?

The Arduino shield, identical to mine, can be viewed here: https://www.osepp.com/electronic-modules/shields/45-16-2-lcd-display-keypad-shield

Thanks in advance

Hi Phil,

Thanks for your help.
I've tested the board and as far as I can understand it works well. The voltages are correct and once mounted on the TI board, the power already reaches LED1 and LED3.

It happened to me the same as to Zan ("the display connector pins projection under the board fouls and shorts into one of the small jumpers on the board if it's pushed fully home", but tomorrow I will cut the pin concerned so that the assembly stay robust.

If it wasn't for Zan's message I would still not be aware of the problem, because I don't have the display yet so I can understand what's going on...

For those who have not yet assembled the board and since the terminal block once assembled covers some of the information printed on the board, it may be a good idea to take note of that information before mounting for ease of use.

Hi Phil,

just finished assembling the components on the board and I don't think I made any mistakes.
However, if possible, I would like to test the assembly before moving on. Can you, please, tell me if there are any tests I can do to make sure I haven't screwed up?

Thanks in advance

Hello Phil, good evening.

Components arrived safely in yesterday’s Post.
Thank you Phil.

Best regards

Hello Phil,

I agree with Zan. Please do so.

Hello Phill,

I'm sorry Phil, my message dated 03-11-2019 should have been written as follows:
Yes, please, I'm interested in the component set.

Best regards

Hello Phill,

Not yet! Friday was holiday here. Perhaps will arrive tomorrow
Thank you for your care.

Hello Phill, Good morning.

I'm interested in the kit of parts.
Thank you.

Hi Phill,
I am portuguese and I live in Portugal.
If you still have an available PCB I would like to have it.
If there is such a possibility I do not know how I can pay you for the board and all expenses. Will it be possible through PayPal?

Best Regards
Dias Costa

Hi Iain, good morning.

You cant try ***HERE***
Withou looking further I found a variation.

For searching I used "window keeps GU" , being GU one maker of PVK keeps.

Hello Dave,

I'm interested in building an ELS for my EMCO Compact 8 lathe, so I started looking for an incremental rotary encoder that can be used in the project.
As I just know - from what you wrote in your post - that the rpm must be at least 4000 - I searched and found a rotary encoder **HERE**
Could you please tell me if, in your opinion, his specifications are compatible with my objective?

Grateful
Dias Costa

Hello Ricky,

I started building a shaper based on Gingery's book, with modifications, but I have not figured it out yet.
You can eventually collect some information from the photos that you will find **HERE** and / or from the little film that I made and that you will find **HERE** in the following URL:

Hello Howardt,

Thanks for the clarification.
I will have to review my (short) knowledge about files.

greetings
Dias Costa

Hello Mike,

If in your message you mean that the Tomé Feteira files are of Swiss manufacture, you are wrong.
They are, in fact, manufactured in Portugal.
Read, please, the text you can find ***HERE*** .

Hello ChrisH!
Hello Brian!

I have been away from home and just today I was able to prepare myself to begin the work of drawing the links between the Arduino tb6560 driver and the power supplies.
Thankfully I read the news in the forum first.
Dave's very well-done work (SillyOldDuffer) far surpasses everything I could do. What's more, it uses a driver (tb6600) which seems to me to be more complete and sturdier than what I use (tb6560).
I'm really tempted to get a tb6600 driver and follow Dave's instructions for assembly.
If, after all, I can be of service to you, please let me know.

Greetings
Dias Costa

Hello ChrisH,

I started building a system for lead screw control for my lathe but I have by now stopped its development.
The materials used and the point where the building is is as follows:
Motor: NEMA23 (double axle and long purchased at Arceurotrade)
Driver: tb6560 (around £10 in Amazon)
Controller: Arduino Mega (may be Arduino Uno)
Motor Power Supply: 24Volts, 6.5Amperes
Power supply for Arduino: 5Volts, 1.5Amperes

All connections are made (they are temporary) and the program on the Arduino already controls the motor.
I have tested the system with the engine running (without load) for many hours and it does not even heat up.

If you want I can make a very simple drawing of the connection diagram.

Hello Daggers, good evening.

First of all I must say that I am not an electronics expert.

One possibility is to use a Hall effect sensor (very small) fixed at each end of the course of the cross slide and a very small magnet fixed at each end of one side of the cross slide.
The sensor is very easily understood by the Arduino and the necessary code exists available as an example on the WWW.

I am experimenting with the use of Hall sensors and magnets (4mm diameter and 2mm thickness) to detect and control movement of a disc mounted on the spindle of the lathe and using the information gathered to control the rotation of the lead screw.
The Hall sensor I use has the SS49E reference.

Additionally, I call your attention to a driver that I am also using in this experience that has also proved very easy to use with Arduino. It is currently controlling a stepper motor and the programming was also easy (perhaps because I was professionally a programmer). That driver is referred to as TB6560.

If I can help you please feel free to ask.

Note:
Not being English my mother tong perhaps I wrote some wrongs or was not clear enough. If so I beg you, please, forgive me.

Best Regards
Dias Costa
