RPi4 with Mesa 7c81 + other BOBs (?) ($89 + $??) Would like to start with only a router (not a controlled spindle) but can see upgrading in the future. Topic started 19 Apr 2023 01:01, by andypugh. It is possible to drive a GS2 from the serial port. Might not be a bad idea to start (or just think about) another pinned post "Mesa Card Examples". Just did a quick test and found some bugs:-7i96S is always named 7i76S, should be 7i96S-see attached, 6 inputs 4 outputs 1 enable 4 stepgens 1 encoder and 1 spindle comes back with 7i76S (should be 7i96S) and 7i77 and all combos using 2 cards, while everything should be only a 7i96S Click that Done button and then Yes and open up your configured LinuxCNC! Now for all of the fine tuning that will be covered in a different guide. Create a format, perhaps similar to what I did above, and people can post a summary of their machine for others to use as inspiration. 085 seconds Powered by Kunena Forum. . I have purchased 2x 7i96s Mesa cards. mesa card. MPG Pendant is a must, but may need to be an upgrade as well. Many FPGA cards can additionally connect to Peripheral Cards Anything I/O Cards Motion Control LinuxCNC Supported Boards - Plug-N-Go Kits - Anything I/O FPGA Cards - Anything I/O Daughter Cards - DB25 Daughter Cards - Anyone who has studied LinuxCNC will have come across the term "mesa cards". Yes, a 7I76E (or 7I96) is a combined FPGA/controller card and breakout The 7I92 is just the FPGA/controller part and needs a Mesa or parallel port compatible breakout board if not used with a integrated drive/Breakout like a Gecko G540 or Leadshine MX3660/4660 LinuxCNC Supported FPGA-cards. As a newcomer to LinuxCNC and Mesa products I struggled to get may head around the 7C81 interface card and how it all fits together. The firmware is open source, portable and flexible. bit file using mesaflash (or mesaflash3), I get the message "No 7i92 board found". LinuxCNC Forum. Can someone please help me get started setting up my Mesa-cards with LinuxCNC? I plan on using the following setup: PC running LinuxCNC -> 7I94 -> 7I77 (for analog servo-motor control with encoder feedback and general I/O in the main control cabinet) I have two general question with regards to linuxcnc with mesa cards. Last Post by andypugh LinuxCNC IRC (real-time chat) is moving to Libera. Driver Boards. Sort By: 4I69-16-AIN FPGA based PC104-PLUS Anything I/O card The MESA 4I69 is a general purpose programmable I/O card. Oh and each Mesa has at least 2 of those very fast parallel ports, and is not limited on what pins can do as the parallel port is, Mesa can do anything on any port at ridiculously high speeds. 4I69-25 FPGA based PC104-PLUS Mesa cards are add-on cards that offload the high-speed tasks to an FPGA. The only daughter board i can find that seems to have encoder inputs as well as step/dri outputs is the 7i85S. You should not use relays in a safety circuit unless it is a standards approved safety relay. So when you push the button it cuts the mains power and lights up a Mesa input to tell Linuxcnc estop has been pressed. 121 -- so the ethernet connection is working fine.

As an example cards with three of these connectors have 3x24 I/O pins while the new 3x20 has six connectors for 6x24 I/O pins. Toggle Navigation Remember Me Log in Forgot Login? Sign up Index; Recent Topics; Search; www. This is a case of Mesa being annoyingly too careful with the card details. Many of the MESA FPGA-cards use 50-pin connector that has 24 I/O pins, 24 GND-pins, and Power (GND+VCC). A bigger FPGA allows more complicated firmwares. There is no real advantage of the older 5I20/5I22 FPGA cards systems for motion control Unless you have more than 12 axis, or 400 I/O points, the FPGA on a 5I25 has plenty of space 2) It uses ports on the Mesa card. My Uspace install pages. Driver Mesa Card Combination Tool. 1) Should/Would one expect any noticeable difference in the performance or operation of linuxcnc when using something like the Mesa 7I76-6i25 combo, compared to a normal parallel port config.

Mesa cards are not motion controllers, nor do they buffer commands from the PC as with Mach3 & ESS boards. 1. But when I saw the moving machine with recommended parameters and It moved really slowly I decided to buy mesa card sooner. Time critical (realtime) tasks are performed on the FPGA card. First decision is which connection method is used as this will depend on your computer hardware: • Ethernet Ethernet cable from the LCNC computer (PC or Raspberry Pi) to the Mesa FPGA card The future upgrade had to be mesa card. Replies: 0. Views: 3917. The newer HostMot2 driver works with all the [Anything I/O] boards. A typical application would be to re-purpose the smart-serial port on the 7i96 as a modbus port to control a VFD. It can be configured (at compile-time) with zero or more instances (an object created at runtime) of each of several Modules: encoders (quadrature counters), PWM generators, and step/dir generators. 00 Add to Cart. Topic started 18 Feb 2024 20:42, by klopp. Mesa FPGA cards can connect to LinuxCNC through PCI, PCIe, EPP parallel port (7i43, 7i90), Ethernet and SPI interfaces. MESA cards was created by Keep in mind that stepper with encoder feedback and loop closed in LinuxCNC behave like servo systems, so a Mesa cards are a different beast, although some can do parallel port stuff/pinout, but at a much, much faster rate. hal file, then communicates with Mesa card to get its config; Linuxcnc then treats the external device as if its physically connected. Searching through the forum I see the following: arghh, looks like I sent out some 7I76E cards with the card name not set. 7I97T main board -> P1 connector -> 7I85 The 7i74 is an RS422 breakout for the Mesa Smart-Serial remote cards (7i64, 8i20, 7i77 etc). I can ping 192. Realtime Short guide to setup your new Mesa control board for LinuxCNC ¶ Mesa 7i96 Setup Guide When you are setting up your Mesa board for the first time, make sure you have all of your settings in mind so you know what to input when the The mesa cards available in the selection box are based on what PnCconf finds for firmware on the systems. This becomes a compliant system. Ethernet Connected Boards Thanks JT! I think I will skip the 50-pin cards as well as the DB25/IDC26 cards with more than two channels - I'm under the (perhaps mistaken?) impression that those cards are seldom used by beginners, for MESA cards Start; Prev; 1; Next; End; 1; ajc771; Offline; New Member More. Wouldn't want anyone to throw money at something that doesn't work yet (grumble grumble grumble). Don't know what I don't know yet, but there is so much more to read LinuxCNC Supported FPGA-cards. 255. 2 7i74 and any of these, 8 in total plus the one connected to 7i76E: 7i70 - 48 inputs 7i71 - 48 sourcing outputs I'm designing a 6 axis robot with the intent of using absolute encoders on all axis and am wondering what type of absolute encoders can be interfaced to mesa cards and Linuxcnc? From bit of googling I gather that SSI encoders can be used but can SPI or RS-485 encoders?. New realtime-modbus driver for Mesa cards. chat. I have a 7i92M card and when I try to download a . I . " Additionally, the config tool can "Firmware Flash, Reload, Verify Mesa cards", Great work, just for the direct connection (spi), might be an idea for the time being to mention the RPi5 is unsupported at the moment. org; Hardware & Machines. Replies: 9. Two drivers are supported by LinuxCNC. Last Post 19 Apr 2023 01:01 by andypugh. - the Mesa card is not able to participate from routing, a gateway can not be configured - the Mesa card has to be in the same logical network than the LinuxCNC computer - the Mesa card always assumes to be in a class C network (suffix /24, network mask 255. If you already have a Mesa card then this means that no extra hardware is needed. But what are these cards actually and why are they so suitable for self-building or retrofitting a CNC The [MESA Anything I/O] boards are FPGA-based, and can run with different firmwares. There are options to add custom firmware and/or blacklist (ignore) some firmware or boards using a preference Can someone please help me get started setting up my Mesa-cards with LinuxCNC? I plan on using the following setup: PC running LinuxCNC -> 7I94 -> 7I77 (for Luckily by using the Mesa card to do the work that requires the fastest response time (encoder counting and PWM generation) we can endure a lot more latency then if we used the parallel port for these things. Last Post 26 Apr 2024 12:51 by tommylight. RPi4 with Mesa 7i76e ($199) 3. Just trying to get a feel for what I could expect. 1. The 7I77 is daughtercard/breakout board for use with MESA's 25 pin I/O FPGA cards like the 5I25. At a later date, I plan to reconfigure the machine, and will instead want to drive 8 servo motors plus a spindle. 0000 MHz IDROM Type: 3 Instance Stride 0: 4 Instance Stride 1: 64 Register Wire the mains power to your motors through the NC side and wire field power through the NO side. The interface between LinuxCNC and the card is Mesa cards are add-on cards that offload the high-speed tasks to an FPGA. The FPGA runs a firmware known as "" The interface - Page 2. For a step/dir setup I would use a 5I25/6I25 + 7I76 card set, for a analog servo setup I would use a 5i25/6i25+ 7i77 card set. Time to create page: 0. Maybe the images below will help the someone to get a clearer understanding of the 7C81 and how it all fist together. Hi folks. The smart-serial protocol is proprietary to Mesa, and not suitable for driving a GS2 (As far as I know). Peripheral Cards Anything I/O Cards Motion Control LinuxCNC Supported Boards Analog Interface Adaptors & Cables Miscellaneous charges. The older Hostmot-4 firmware /driver is most mature, but only works with the 5i20 and is no longer actively developed. I think that the smart-serial cards from Mesa use a dsPIC rather than a µP like the STM32. 4 - FPGA CARDS PC CONNECTION Mesa offers FPGA main cards with a variety of different PC connection types. Anything I/O FPGA Cards. In fact as far as the system is concerned it is a normal smart-serial card. They are working on a web-shop. The 7I77 is designed for interfacing up to 6 Axis of analog servo motor drives and also provides 48 isolated I/O points for general purpose field I/O use. If you do not have a Mesa card then this is obviously no advantage at all. Or am i just confused and you can use any of the daughter cards and just setup the pins for there needed use? I'm putting together a machine running linuxCNC and will need to drive 7 stepper motors + minimal I/O for limit switches, etc. You can 100% trust Mesa, many of us know PCW personally. 0), a different network mask can not be configured Linuxcnc load the driver from the. 0000 MHz Clock High frequency: 200. RPi4 with Mesa 7c80 ($249) 2. Payment instruction by Lily Wun is to fax my card details over. I managed to persuade them to let me send the information in two separate emails, if I recall correctly.
