The 527F requires the rigid tapping software to be installed, see OPTIONS command to display status. Next the machine must support rigid tapping see this post to help determine if machine supports rigid tapping: https://www.calmotion.com/forum/_527f/add-rigid-tapping-capabilities-to-the-cnc-control Basically the setup is 99% the same as the Fadal, the RAMP and GAIN numbers will be typically be a bit different compared to what the CNC88 would end with. Use the instructions attached. You auto tune the drive. Using the Fadal service tool thread you adjust the GAIN and RAMP for the Rigid tapping in SETP: Required FADAL SVT0077 Rigid tapping gauge    Rigid tapping calibration, See attached procedure, and video: https://drive.google.com/open?id=1Frf5tQnAhnlMEB09GebM3MFLhziJb4R9 "Gain is too" low video: https://drive.google.com/file/d/1uVEnTssDEUBuGOeUoRTG8jDcsoKIag6-/view?usp=drive_link "Gain is just right" video: https://drive.google.com/file/d/1WpJMKpPai9EpYQgWmX3RvITrRkIX9F04/view?usp=drive_link

If you just got your machine and it came with a Calmotion USBCNC-FAD or a LANCNC product, but the original owner gave you no instructions how to use the unit? Search Youtube for "Calmotion USB" there are several videos including diagnosis problems to be found there. First you will need to determine what baud rate the Calmotion is set up for. This depends on what the original owner set it to. Typically the Calmotion default is to use CD,10 but this doesn't guarantee what the previous owner changed. Here are the steps to get your Calmotion working: 1. Make sure the unit is powered, look for the LEDs on the board or connectors. 2. Depending on the unit, when the USB disk is inserted, another LED should light, but this varies with which product is installed 3. Find the baud rate currently set by entering every possible CD,# until the unit responds with the help menu. Start with CD,6, press enter, the Fadal should Immediately return to the ENTER NEXT COMMAND, then press the + key only (no enter). Wait a couple seconds, if the help menu does not appear then go to the next #: CD,6<enter> + {wait for help menu?} CD,7<enter> + {wait for help menu?} CD,8<enter> + {wait for help menu} CD,9<enter> + {wait for help menu} CD,10<enter> + {wait for help menu} CD,11<enter> + {wait for help menu} CD,12<enter> + {wait for help menu} Once the CD,# has been found, then insert your USB disk and display the directory: CD,#<enter> DIR+ If nothing has worked. Take a picture of the unit that is 1) installed, 2) how it is powered, 3) cables connected and 4) the USB disk format (must be FAT32) . Send all this information in an email to support@calmotion.com .

Here are some issues that can happen Fadal machines and some tips to solve your issues. Typically this happens on early Fadal machines that the control cards were updated, but did not receive all the wiring upgrades found on newer Fadal cabinets. Issue: 1. is running in Auto, and the machine will randomly go into SLIDE HOLD 2. A keypress will be missed. When typing X10.222 but the zero is skipped 3. Jog wheel loses pulses when turning the MPG 4. Jog mode issues Possible solutions: 1. check the 1090 keyboard control revision. If it is not at least the 1090-3A board, which has filter capacitors and a removable software EPROM, then this is definitely the root problem. Update to at least the 1090-3A with the latest software, this is usually the solution that directly addresses the problem 2. Fadal increased the gauge of the +5 and DC ground wire going the 1090 power terminal. Fadal ended up using a very large gauge red and white/black wire to power the 1090. At least 12 AWG. This improved the voltage drop all the way to the pendant as well and improving the noise on the DC ground. 3. Improve the chassis green ground wires by increasing gauge, reference a late 1990s built Fadal electrical cabinet the used larger gauge wire as well as single point chassis grounds. 4. The keyboard signals are on a 26 wire parallel cable that goes back to the 1060 motherboard. Make sure this cable does not run next to any high power wires. Look at the bundle in the top cable tray over the machine, remove it from the bundle if it is wire tied into other wires. 5. Make sure the Feed rate and Spindle % pots aren't shorting onto the front panel. This can create odd intermittent problems. Look for shorts to the panel with a multi-meter. Look for improvements by disconnecting the 2 pots from the panel so they hang in the air not touching anything. If the issues improve, look for where the short on the panel. With a new 527F control upgrade, purchase the Calmotion version of the 1090. The 26pin parallel cable can be replaced with a much more robust RS-485 serial connection using CAT5 cabling. Contact Calmotion with a picture of your current 1090 card and the set of 527F control cards in the 1060 motherboard. Calmotion will help selecting the correct parts to update the keyboard controller.
