Hey Jan, you say “centimeters matter” and I can understand you can have such a situation in your workshop. But wouldn’t it be better to reserve more space for future modifications? Already the [spindle drop](https://forum.onefinitycnc.com/search?q=spindle%20drop) problem on the new [Z-20 assembly](https://www.onefinitycnc.com/product-page/z-20-heavy-duty-z-slider) found on Elite machines leads to people seeing the need to retrofit stepper motors with brake or balancer springs. But also the fact that the stock [Elite drag chains are not sufficient](https://forum.onefinitycnc.com/t/sagging-drag-chains/22230), neither for retrofitting anything at all, but **not even sufficient for the promoted spindle option hoses and cables** would suggest not trying to fit it with the least possible centimeter. I think you should consider [space to reserve around the machine](https://forum.onefinitycnc.com/search?q=space%20to%20reserve%20around%20the%20machine%20%40Aiph5u), which means, besides - [Dimensions for building a table for Standard and Elite Journeyman (Cable and Vac Management to start off – Post #14 by Aiph5u)](https://forum.onefinitycnc.com/t/cable-and-vac-management-to-start-off/18753/14) - [Space to reserve around the machine](https://forum.onefinitycnc.com/t/1st-post-size-matters-and-vertical-clamping-for-finger-joints-tenons/18074/3) - [Drag chain width computation](https://forum.onefinitycnc.com/t/journeyman-x-50-drag-chain-addition/17984/2) you could also come to the idea to retrofit **an enclosure** later, because on a CNC router, you not only have wood dust and flying chips, but what about a bit broken, with a bit debris flying around? That’s why… > [@Right procedure to change a bit on a spindle during a job?](https://forum.onefinitycnc.com/t/right-procedure-to-change-a-bit-on-a-spindle-during-a-job/17417/7): > > 1.

Fragments reach high flight speeds and can sometimes cause serious injuries. A separating protective device (machine encapsulation) must therefore be used that protects against flying chips and debris and also has a safety switch that disconnects the frequency converter or the motor spindle from the power supply on all poles(¹) **as long as the encapsulation is not closed**. > > > > > > – Source: Mechatron HFS Series High-Frequency Spindle Operating Manual > > > > That is why [ISO 13849](https://en.wikipedia.org/wiki/ISO_13849) [Safety relays](https://en.wikipedia.org/wiki/Safety_relay) like the [Omron G9SE](https://industrial.omron.co.uk/en/products/g9se) ([datasheet](https://assets.omron.eu/downloads/datasheet/en/v3/j198_g9se_safety_relay_unit_datasheet_en.pdf)) have an input for a **sensor switch on the door of the enclosure** of a CNC machine, which signals him someone opened the door, which allows, if VFD is configured appropriately, to decelerate spindle immediately. > > * * * > > ¹) by ensuring “Safe Torque Off (STO)” mode on the VFD I find [this enclosure concept rather mature](https://forum.onefinitycnc.com/t/the-table-basic/3787/10), see also [here](https://forum.onefinitycnc.com/t/the-table-basic/3787/85) and [here](https://forum.onefinitycnc.com/t/the-table-basic/3787/75) for its integrated dust outlet. I would make it dust-tight and isolated against noise. What this enclosure takes into account and what I find important, is what @cyberreefguru stated in [Cnc Table Hindsight 20/20](https://forum.onefinitycnc.com/t/cnc-table-hindsight-20-20/5965): > [@Cnc Table Hindsight 20/20](https://forum.onefinitycnc.com/t/cnc-table-hindsight-20-20/5965/2): > > To that end, I really wish I could walk around my machine. I only have access from the front and leaning over to get to the back of the machine (clamps, clean, etc.) is quite the pain in the \*\*\*. However I don’t believe Onefinity will provide exact 3D models of their machines. All official drawings up to now have been somewhat incomplete. I hope the links (including the links to the official dimensions) I provided above with dimensions will help you the much possible. --- _[View the full topic](https://forum.onefinitycnc.com/t/cad-models-of-the-machines/22845)._
