Hi im new to this forum so please bear with me
I have a 1996 haas vf6 in great condition*
I am trying to drip feed to it as some of my programs are up to 90mb using a stand alone pc next to the cnc i am using remo dnc by easy dnc
I have all the settings right according to many online posts ive read but i keep getting various error codes*
Parity error
Framing error
Invalid code (even though the program has ran before)
The machine stops moving in xyz but the spindle keeps going
I contacted haas uk to see about a memory upgrade so i didnt have to dnc but they told me i had to replace the whole control pendant at a cost of 12 grand uk sterling
This seems mad for more memory so i dont have to dnc*
Has anyone any experience with the usb to parallel port things you see online where the little gadget replaces the pc see link below from shopfloor automations Usa

Shop Floor Automations - Shop Floor Hardware - CNC Solutions*... b-connect/

Also can the memory be upgraded at a more sensible cost*
You would think it would be a replacement mother board and new memory chip but certainly not 12 grand
All and any help is massively appreciated

That seems like a lot of $$ for memory, but I don't know all that goes into the upgrade. I have not drip fed in many years but someone will come along here with good info.
Also do a search here, you will have to sift through a lot that you dont want but there is a ton of info here to be dug up.

Does your PC have a real serial port, or are you using a USB-RS232 convertor? Some of these aren't reliable enough to put your machine at risk.

Im going from the com port on my pc into the serial port on the cnc

Have you tried decreasing the baud rate? We have an old machine (1993) which doesn't like using any baud rate faster than "4800" when communicating with the nearby windows XP desktop computer that we use for it. I don't know why but it does indeed reliably transfer at 4800 so leave it there.
The other RS232 settings don't matter much (parity, Xon/Xoff, etc) so long as they match between the CNC and PC.
